Changing the product key that you used to install Windows with might be necessary if you find out that your current product key is.. well, illegal, and you've purchased a new copy of Windows to solve the problem.
While it's probably less common these days, many people still use product key generators or other illegal tools to get product keys that work to install Windows only to find out later, when they try to activate Windows, that their original plan isn't going to work out.
You could completely reinstall Windows using your new, valid key code, but changing the product key without reinstalling is considerably easier. You can change the product key manually by making certain registry changes or by using a wizard available in Control Panel.
The steps involved in changing your product key differ considerably depending on which Windows operating system you're using. See our article What Version of Windows Do I Have? if you're not sure.
How to Change the Product Key in Windows 10, 8, 7, and Vista
Since some versions of Windows use slightly different names for some menus and windows pay close attention to the differences that are called out in those steps.
Tap or click Close to close this window. You can now also close any other windows you opened in the above steps.
How to Change the Windows XP Product Key
A completely different process is required to change the Windows XP product key code because you have to make changes to the Windows Registry. It's important to take great care in making only the changes described below!
It's highly recommended that you back up the registry keys you're changing in these steps as an extra precaution.
If you're uncomfortable making registry changes in order to change your Windows XP product key, using the popular free product key finder program called Winkeyfinder is another option. It's an excellent alternative solution to changing the Windows XP product key code manually.

I own a legitimate retail version of Windows 7 serial key. I upgraded my computer to Windows 10.
My friend built a new computer and he has no Windows license. Since I won't use Windows 7 anymore, can I give my license to him, while keeping my free Windows 10?

Your Windows 7 license won't become invalid by updating to Windows 10. However, it is also part of your Windows 10 license, so you are only allowed to have one Windows 10 or one Windows 7 installation at a time with one key.
When I upgrade a preinstalled (OEM) or retail version of Windows 7 or Windows 8/8.1 license to Windows 10, does that license remain OEM or become a retail license?
If you upgrade from a OEM or retail version of Windows 7 or Windows 8/8.1 to the free Windows 10 upgrade this summer, the license is consumed into it. Because the free upgrade is derived from the base qualifying license, Windows 10 will carry that licensing too.
Your Windows 7 license will always be valid and will not be changed or deactivated because of the upgrade to Windows 10: you'll be able to install or restore Windows 7 again in case you'll need to do that (provided that you've the Windows 7 installation DVD

If you're preparing to reinstall a program or an operating system (like a clean install of Windows), you'll need to find your unique product key (CD key) or serial number before continuing.
Normally this product key is located on the original install disc, or maybe in your order confirmation email. If you've lost your product key, you can often find it in the Windows Registry but this can be difficult, or sometimes even impossible, to do. Fortunately, there are many free key finder programs available to help.
Please read our Key Finder Programs FAQ for lots of helpful information. This isn't an easy topic, especially if you're new to it.
Below are the top 20 free key finder programs. We also keep a list of commercial key finder programs but it's highly recommended that you exhaust the options below before paying for one.

Product Key FinderWhat We Like
What We Don't Like

After executing Product Key Finder, a simple window opens displaying your Windows product key along with other product keys and serial numbers that Product Key Finder can locate.

LicenseCrawlerWhat We Like
What We Don't Like
LicenseCrawler is another well put together free key finder tool.
LicenseCrawler differs from other key finder programs in its almost full-text interface, which I like. I found LicenseCrawler to be very effective at finding serial numbers for the many programs on my PC.

SterJo Key FinderWhat We Like
What We Don't Like
SterJo Key Finder is another key finder that finds product keys for over 500 games and software on either the local Windows install (your computer) or a remote one.

Unfortunately, SterJo Key Finder found two different product keys for one of the programs on my computer, which makes it hard to recommend above some of the other programs from this list.

Product Key Finder (OTT Solutions)What We Like
What We Don't Like
Product Key Finder won't win any creative name contests but that's not important — it's a very good key finder program.
I like Product Key Finder because it's designed very well, instantly finds product keys, allows an easy XML or CSV backup of keys found, and also lets you change your Windows registration or product key right from the tool.
Finds Keys for Operating Systems: Windows 7, Windows Vista, Windows Server 2008 & 2003, Windows XP, and Windows 2000.
Finds Keys for Other Software: Most Microsoft Office and other Microsoft programs, and many non-Microsoft applications.

MSKeyViewer PlusWhat We Like
What We Don't Like
MSKeyViewer Plus is another good product key finder program.
Major advantages include a really small size, no install needed, and super easy interface. MSKeyViewer Plus instantly displays product keys–no scanning of your registry required.
Finds Keys for Operating Systems: Windows 8, Windows 7, Windows Vista, Windows XP, Windows 2000, Windows ME, Windows 95/98, and Windows Server 2008 & 2003. 64-bit versions are also supported.

Though the other Windows 8 compatible programs from this list were able to find the product key for my installation, MSKeyViewer Plus wasn't able to do so.
I'd probably pick several other key finders before MSKeyViewer Plus, but if you're having trouble finding a specific key, give MSKeyViewer a try.
MSKeyViewer Plus may find a key for your Windows 10 installation, but it's probably going to be incorrect just like mine was.

Free PC AuditWhat We Like

Finds Keys for Other Software: Microsoft Office 2013, Office 2010, 2007, Office 2003, and likely some older versions, as well as some Adobe and Corel software.
Because there's so much other information shown in Free PC Audit, it can seem very cluttered if you're using it just for finding product keys.

Windows Product Key Viewer is another key finder program that shows the product key for several versions of Windows.
You can easily copy the product key out of the program, print the keys, or save them to a file. Additional details are shown as well, such as the product ID, install date, and build number.

Lazesoft Windows Key FinderWhat We Like
What We Don't Like
Lazesoft Windows Key Finder is another free program that can find the product key for many Windows installs and Microsoft Office versions.

Finds Keys for Operating Systems: Windows 7, Windows Vista, Windows XP, Windows 2000, Windows ME, and Windows 98.
Finds Keys for Other Software: Microsoft Office 2007, Office 2003, and Office XP.
Honestly, I didn't care much for Product Key Informer. I think it was the baked-in fields for specific product keys that bothered me. It's a waste of screen real estate and confirms that the program's product key finding abilities are very limited.

Windows Product Key FinderWhat We Like
What We Don't Like
Windows Product Key Finder is only 80 KB in size, is completely portable, and quickly shows the product key.
Finds Keys for Operating Systems: Windows 7, Windows Vista, and Windows XP.
When compared to other key finder programs from this list, Windows Product Key Finder is extremely basic and void of support for anything but the Windows OS. Also, while it is able to open in Windows 8 and 10, the product key it finds is inaccurate.

Game Key RevealerWhat We Like
What We Don't Like
Game Key Revealer shows the product keys of over 2000 games.
It's completely portable, takes up very little space, and can export keys to a text file or print them off.
Finds Keys for Games: Half-Life, Battlefield 2, Counter-Strike, Mirror's Edge, Halo, Need for Speed, Dead Space, Crysis, Harry Potter, and many more.
In addition to showing the product keys for a few thousand games, keys for nearly two dozen can actually be changed with Game Key Revealer, which could come in handy.

Abelssoft's MyKeyFinderWhat We Like
What We Don't Like
MyKeyFinder lets you save product keys to a PDF file or to the clipboard. You can also send one or more keys to a printer.
You can search through the list of install keys it finds and even blacklist registry keys to avoid finding serials in those locations.
Finds Keys for Operating Systems: Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP.
Finds Keys for Other Software: VMware, some Microsoft Office products, and others.
While testing MyKeyFinder, I found that a scan takes much longer to complete than any of the other programs from this list. Also, it found keys for programs (hundreds of them) that don't actually use serials, as well a key for Microsoft Office 2013 that wasn't correct.
Important Product Key Finder Information (Windows Product Keys)
If your system was purchased with Microsoft Windows pre-installed and you have not reinstalled it or upgraded it yourself, a key finder may only find the generic product key that your PC manufacturer used to install Windows. This product key may not work when attempting to reinstall Windows. In this case, you must use the unique product key that is on the sticker attached to your computer case.
If you can't locate your product key sticker you'll need to request a new Windows product key.
If you’ve used a Windows product in the past two decades or more, you’ve likely encountered a Windows product key. You may have even found immense frustration as your product key and Windows didn’t play ball. With that in mind, we thought it was high time to give you all chance to understand more about the 25 characters governing your system.

This FAQ will shed some light, explain what has changed with Windows 10 version 1511 (Fall Update), and translate activation-related error codes.Read More, and it is now easier than ever to use your existing Windows 7, 8, or 8.1 license to secure your Windows 10 upgrade (until July 29, 2016). But what about all of your old licenses? Where are they? Where have they gone? And most importantly, are they actually of any use to you now?
Let’s take a look at everything you need to know about Windows product keys.
In this article:Basic Terms | How to Find Your Windows Product Key | Windows 10 Activation | Digital Entitlement Pre July 29 | Digital Entitlement Post July 29 | Pre July 29 Free Upgrade to Windows 10 | July 29 Cutoff | How to Link Your Windows 10 License with Your Microsoft Account | Using Windows 10 Without a Product Key | Windows 10 Downgrade Rights | Changing or Uninstalling Your Windows Product Key | How to Find Your Microsoft Office Product Key | 4 Tools to Find Product Keys
Some Basic Terms
I’ll repeatedly refer to some basic terms throughout this article, so it’ll make all of our lives easier if I clarify exactly what I’m talking about, right now.
We’ve also included some handy “timeline reminders” for those wondering how long they have left to implement the free upgrade, and for those specific questions regarding product keys and the discontinuation of the upgrade path.
How to Find Your Windows Product Key
A big question to get us started. How do you find your Windows product key? If you head to Control Panel > System and Security > System underneath Windows Activation you’ll spot your Product ID. In Windows 10, you’ll also find the Product ID under Settings > System > About. This isn’t the same as your Product Key. It is created during the installation process and is used to qualify your version of the operating system.
So where is it?
You can use the Magical Jelly Bean Keyfinder to locate it. Download and install the application. When it opens, your Windows License Key will be displayed in the right hand panel next to CD Key.
As you can see from the screenshot above, I’m using Windows 10 Pro at the moment. Before any readers exclaim “You lunatic, don’t display your product key to the world,” this is actually a generic key assigned to all Windows 10 Pro users. If you’re a Windows 10 Home user, your key will be TX9XD-98N7V-6WMQ6-BX7FG-H8Q99.
This is due to the Windows 10 upgrade and entitlement processIs a Windows 10 Pro Upgrade Worth $99?Is a Windows 10 Pro Upgrade Worth $99?Windows 10 Pro offers more features, but also carries a $99 price tag to upgrade from the Home edition. Here's what you need to know to decide if professional features are worth the upgrade.Read More, which I will explain in more detail in the next section.
If you’re using an earlier version of Windows, Magical Jelly Bean Keyfinder will display the product key you used during installation. For example, the below image shows the program working in Windows 7.
What’s Up With Windows 10?
When Windows 10 was released a year ago, Microsoft attempted to make the upgrade process as easy as possible. Your product key wouldn’t be needed in the process, as you’d be upgrading from a legitimately licensed version of Windows 7, 8, or 8.1.
As was typical for Windows 10, even the seemingly easy became confusing. Information surrounding the upgrade process was conflated between the countless media outlets attempting to assist millions of users, and many were left with more questions than solid answers.
Above, I’ve shown you the generic product keys issued to those users who upgraded to Windows 10. Now you may be wondering where your actual Windows product key has gone. After all, you paid for your Windows 7, 8, or 8.1 license all those years ago and, if it was a retail version, you might want to move your installation elsewhere.
Digital Entitlement Pre-July 29
The free Windows 10 upgrade process is called Digital Entitlement, and it links your Product Key to the hardware you’re upgrading on. The installation process creates a unique installation ID for your system.
As such, the product key for your existing installation – Windows 7, 8, or 8.1 – is “absorbed” during the upgrade process. That doesn’t mean it no longer exists, rather, it has been marked in the big Microsoft Windows 10 upgrade database as used. If you reinstall Windows 10, Microsoft will recognize your system hardware and validate the installation, provided you’re not violating the rules of the licensing agreement.
Did you just ask “But what does that mean?”
It means license types remain the same. A retail license is still a retail license. An OEM license is still tied to a single machineWhat Are OEM Products and Why Are They Cheaper?What Are OEM Products and Why Are They Cheaper?OEM stands for original equipment manufacturer. Should you buy OEM products, or is there a catch that'll set you up for trouble?Read More. Volume licenses are still only assigned to massive organizations, and so on.
If you’ve upgraded, but forgotten or misplaced your original license key, or simply want to view the license key you upgraded with, you’ll need to download ShowKeyPlus. The download link is at the very bottom of the linked page. Once downloaded, extract the files, and run ShowKeyPlus.exe.
As you can see from the below image, it very much shows your original key (hence why it is scribbled out!).
Got it? Write it down, and put it somewhere safe.
Digital Entitlement: Post-July 29
July 29 will see the end of the free upgrade path to Windows 10, but that doesn’t mean Digital Entitlement will disappear. But you may well be wondering what will happen to your free version of Windows 10 if you upgrade your hardware. Here is the lowdown:
It presents a difficult scenario. Those Windows 10 retail license holders (via the upgrade path) will assume their new product key is as easily transferable as older Windows licenses, but it doesn’t appear to be the case. Microsoft hasn’t targeted those installing and regularly moving operating systems with this upgrade. If this scenario, which is seeming more and more likely, is the absolute truth, there will be some very disgruntled individuals.
Microsoft has essentially traded a retail license for an OEM license. However, Section 4(b) of the Windows 10 End User License Agreement states:
If you acquired the software as stand-alone software (and also if you upgraded from software you acquired as stand-alone software), you may transfer the software to another device that belongs to you.
Which, to me, feels like a backdoor around their own licensing statements. Unfortunately, until July 29, we can only speculate.

Always Check…
If you purchased a system with a pre-installed version of Windows, check the underside of your laptop or side of the computer case. Your system should have shipped with a label detailing the version of Windows initially installed, and the product key to activate that copy. The inclusion of COA (Certificate of Authenticity) stickers started with Windows XP, and has been present with every version of Windows since that time.
In some cases, the COA sticker is required to confirm a legitimate license. If you have a pre-installed version of Windows, but change the casing of your computer (but not the system hardware), you will need to remove the sticker and either keep it safe, or reapply to the new case.

Create Installation Media
First, we need to make some Windows 10 installation media. I’m not going to detail exactly how to do that here, because I’ve already written a guide on how to do thatHow to Create Windows 10 Installation MediaHow to Create Windows 10 Installation MediaRegardless of how you arrived at Windows 10, there's a way to create your own installation media. Sooner or later you might need it. Let us show you how to be prepared.Read More, as well as a list of software you can use to make the USBCreate a Bootable USB From an ISO With These 10 ToolsCreate a Bootable USB From an ISO With These 10 ToolsWant to create a bootable USB drive from an ISO file?

However, please be sure to make an installation media that matches your existing license e.g. Windows 7 Home will activate Windows 10 Home, and so on.
Create a Virtual Hard Drive
Once that is done, open Computer Management. Windows 7 users can use the Start menu search bar, while Windows 8, 8.1, and 10 users can use the Windows + X shortcut, selecting Computer Management from the menu. Right-click Disk Management in the left-hand column, and select Create VHD.
Copy the setup in the image below:
You’ll have to wait for the virtual hard drive to be created, but when finished, it should automatically appear at the bottom of your storage devices list, like so:
If not, right-click Disk Management again, this time selecting Attach VHD. Browse to the VHD we just created, and it should automatically mount for you.
Begin a New Windows 10 Installation
Insert the Windows 10 USB installation media you created earlier, and boot your system. Move through the standard language selection and license confirmation screens, until you get to the Where do you want to install Windows? screen. Press Shift + F10 to open a Command Prompt. Now type the following commands, in sequence, pressing Enter after each entry:
Now close the Command Prompt, and refresh the list of disks available for installation. Select the newly added disk, and ignore the message saying Windows cannot be installed on this drive. It can, and it will. Press Next.
You’ll now have to wait for the operating system to install as normal, so you could be in for a little wait. When the time comes, enter your old Windows license key, and it should activate.
When you have a new system, you can easily transfer the product key to the new installation, safe in the knowledge you activated and secured the free upgrade to Windows 10.
The July 29 Cutoff
Microsoft has confirmed the cutoff date for the free Windows 10 upgrade path will be July 29, as was stated long before the release of the operating system.
The free upgrade offer to Windows 10 was a first for Microsoft, helping people upgrade faster than ever before. And time is running out. The free upgrade offer will end on July 29 and we want to make sure you don’t miss out.

Only those employed by Microsoft know what will happen after the July 29 cutoff point, but I imagine it will see the end of the free upgrade path.

How to Link Your Windows 10 License to Your Microsoft Account
Timeline: Anytime
A Windows 10 Insider Preview released in June saw a licensing features designed to enable a direct link between a Microsoft account and a Windows 10 license key. This feature will be coming to all Windows 10 users in the upcoming Anniversary Update, Windows 10Windows 10 Anniversary Update Due in July & These Are Its Best FeaturesWindows 10 Anniversary Update Due in July & These Are Its Best FeaturesYou will love the Windows 10 Anniversary Update! The second big upgrade to Windows 10 since its launch in July 2015 is expected this summer. Here we highlight the most exciting features.Read More. But what does it actually change?
The Windows 10 activation process relies on a unique installation ID, created during installation and directly linked to the hardware on which Windows is installed. Now, this unique ID is linked to the system hardware – not a person. If you reinstall Windows 10 on the same system hardware, it should automatically activate.
Conversely, if you attempt to activate Windows 10 on a different system, activation will likely fail, even in cases where a retail key is in use. The link between Microsoft account and a Windows 10 product key is set to address. Changing your motherboard will result in a newly generated unique installation ID, and under the existing rules, you’d have had to pick up the phone and manually activate your version of Windows 10.
Making the Link

Here's how to create a local Windows 10 login account instead.Read More. Those signing in with their Microsoft account will find their Windows 10 license automatically linked to their account.
Press Windows + I to open the Settings panel. Head to Update & Security > Activation > Add an account. Enter your Microsoft account credentials, then click Sign In. You may be challenged for your Local User Account password. If so, provide it, and press Enter. Once the process is complete, you should spot a new message stating “Windows is activated with a digital license linked to your Microsoft account” on the Activation page.
It seems like a sensible move that will appease those users irritated by the sometimes archaic licensing terms metered out by Microsoft. On the other hand, I’m sure that removing some of the anonymity behind the unique installation ID and replacing it with a very definite link to an identifiable email address will rile those who believe Windows 10 and its telemetry is simply an enormous spying program (it isn’t).
Changing, Uninstalling, Or Activating Your Windows Product Key
Timeline: Anytime
There are times when it is necessary to uninstall your own product key from a system, but leave the operating system intact. For instance, you might be selling an old laptop or computer, and want to provide an up-to-date version of Windows 10 for the purchaser – but not your own, activated version. Similarly, if you have a Windows retail license, you may wish to activate your copy of the operating system on a different system.
In these instances, it is possible to uninstall your product key.
How to Uninstall
Open an elevatedCommand Prompt. Windows 8, 8.1, and 10 users can use the Windows Key + X shortcut, then select Command Prompt (Admin). Other users can type CMD in the Start menu search bar, then press Shift + Ctrl + Enter. Now copy and paste the following command15 CMD Commands Every Windows User Should Know15 CMD Commands Every Windows User Should KnowThe command prompt is still a powerful Windows tool.

This command uninstalls the existing product key. Wait for moment, and press OK when the dialogue box appears.
Now copy and paste the following command, and press Enter:
This command clears the uninstalled product key. That’s it!
Please note that uninstalling and clearing the product key do not remove it from the Microsoft activation servers. If you have an OEM version of Windows, your license will still be limited to one system, the license matched to its hardware. Retail users may find that despite their ability to reuse their license, it may require phone activation if online activation fails.
How to Change Your Product Key
Open an elevatedCommand Prompt. Windows 8, 8.1, and 10 users can use the Windows Key + X shortcut, then select Command Prompt (Admin). Other users can type CMD in the Start menu search bar, then press Shift + Ctrl + Enter. Now copy and paste the following command, replacing the number [#] signs with your own product key, and press Enter:
You can use this command if you’ve purchased a new system with an existing Windows installation, but want to switch to your own version.
Check Your License Expiration Date
Logically, you’d think your Windows license will last until the end of time. This was true for all versions up to the release of Windows 10. Furthermore, you might be using a license granted by an educational facility, or through your workplace, and these licenses can come with a limited time of use.
To display the information, open an elevatedCommand Prompt. Windows 8, 8.1, and 10 users can use the Windows Key + X shortcut, then select Command Prompt (Admin). Other users can type CMD in the Start menu search bar, then press Shift + Ctrl + Enter. Now copy and paste the following command, then press Enter:
slmgr /xprYou can also check the license expiration date using winver. Type winver into the Start menu search bar or Cortana search bar, and select the first option. You can see the difference between Windows 10 versions below. On the left is my Insider Preview version, the right is my Windows 10 Pro version.
My Windows 10 Insider Preview version is set to expire in October, whereas my Windows 10 Pro license has no expiration date.
Activate Windows Online and Offline
If Windows fails to activate during the installation process, you can attempt to manually activate your product key. Open an elevatedCommand Prompt. Windows 8, 8.1, and 10 users can use the Windows Key + X shortcut, then select Command Prompt (Admin). Other users can type CMD in the Start menu search bar, then press Shift + Ctrl + Enter. Now copy and paste the following command, then press Enter:
Similarly, if your activation fails and you’re not connected to the Internet, you can use the following command to get an installation ID:
Once you have the installation ID, you’ll need to call the Microsoft Product Activation Centre. They’ll give you an activation ID to enter in the Command Prompt. Once again, open an elevated Command Prompt, and enter the following command:
Insert the activation code Microsoft provided in place of ACTIVATIONIDGOESHERE. This will allow you to activate your installation without an Internet connection.
Using Windows 10 Without a Product Key
Windows 10 has been surprisingly kind to those users without product keys. Whereas Microsoft made Windows 7, 8, and 8.1 functionality diminish over time, they’ve seemingly allowed users to continue using Windows 10, albeit with slightly reduced functionality and the addition of a watermark.
That said, the reduced functionality is unsubstantial, and focuses largely on the cosmetic side of the operating system. Users who’ve been using Windows 10 without a product key have reported consistent feature and security patches, as well as minimal nag-screens to actually purchase a legitimate product key. It really runs against the experience of those users with legitimate licenses on earlier operating systems hounded by the progressively intrusive update screens.
However, it could all change with a single update – but that doesn’t look like happening any time soon.
Windows 10 Downgrade Rights
Certain versions of Windows are eligible for downgrade rights. This is the process of downgrading your current operating system to one of its predecessors. It works differently for different versions, and some aren’t eligible at all. Let’s take a look.
The key article for many in the above table will be the lack of downgrade rights for retail licenses. If you have a specifically purchased license for a single operating system, that is what you’ll be using. Those with an OEM license have an array of downgrade options to choose from:
This shouldn’t be conflated with the opportunity to downgrade Windows 10. If you followed the upgrade path from Windows 7, 8, or 8.1 to Windows 10, you had an option to downgrade, returning to your original operating system, everything exactly where you left it. Windows 10 would delete your Windows.old folder (containing your previous setup), assuming you were now settled in your new home.
These downgrade rights require a clean install, using specific installation media, and (that’s the catch) a valid license key of the Windows version you’re downgrading to.

4 Tools to Find Product Keys
To round our guide to Windows Product keys off nicely, I’ve included a short list of free product key finding tools.
Each of these tools will reveal your Windows product key. ShowKeyPlus, which we used earlier in the article, will also reveal the product key you used to upgrade to Windows 10, which can be very handy. The other three – Magical Jelly Bean, ProduKey, and SterJo Key Finder – will also show any other product keys installed on your system.
Now You Know
We’ve covered a massive range of Windows Product Key information. Most relates to Windows 10, but there are also some handy tips on where to find and how to extract product keys from older versions of the operating system.
We’ve looked at where your product key heads when you follow the Windows 10 upgrade path, and just how you can find your old Windows 7, 8, or 8.1 product key for future reference. We’ve also looked at how you can make the most of any extra license keys you have lying around, making sure they don’t go to waste if and when the year-long free upgrade period ends.
Contrary to belief, Microsoft isn’t always moving the licensing goalposts. They’re actually pretty consistent, but it is understandable that with a relatively new system in place for Windows 10, there would definitely be some confusion. I hope we’ve absolved any muddles or mix-ups you’ve been struggling with!

In short, no, OEM keys are only good for their respective 32-bit or 64-bit versions.
If you had the retail product, you can use the serial number for either.

When I bought Windows 7 I got both the 64-bit and 32-bit version in the box. And just one serial number. So I think it might work.
But why would you want to use 32-bit instead of 64?

MSDNAA serials work on both 32 and 64 bit versions even if they are for the other-bit version. I guess that applies to the non-MSDNAA keys, too.
