Windows XP Operating system
Windows XP is an operating system created by Microsoft in 2001. Soon after its release, it became the most widely used personal operating system in the world.
Even today, it has thousands of users, despite the fact that Microsoft stopped providing support in 2011. There are no new updates available for this operating system.
You can’t update your Windows system by using a Windows XP serial key. If you’re still using this version of Windows, your system will work just fine, but it may cause some security issues on your computer.
Still, if you’re searching for a Windows XP product key, you have landed on the right page. Windows XP activation keys aren’t easy to find these days, but we have some working keys here. Try your luck with any of the free Windows XP keys found below.
Do you need a serial key to install Windows XP?
Windows XP has two types of licensing agreements.
1. VOL (Volume Licensing for Organization)
2. VLK (Volume Licensing Key)
If you have a copy of the Windows XP CD/DVD and you notice “VOL” written on it, you don’t need a Windows XP product key. You can install your copy of Windows without providing a serial key.
On the other hand, if “VLK” is written on your Windows CD/DVD, you have a retail edition of the operating system. You need to provide your genuine Windows XP product key to install the operating system.
Where is your Windows XP product key?
If you have the original Windows XP CD/DVD, the serial key is written on the box. If you can’t locate it on the CD/DVD or you don’t have the original CD/DVD, you won’t be able to find it easily.
Manually locating the Windows XP product key is nearly impossible because of the various encryptions that Microsoft uses. Therefore, your only options are the following.
Extract it using a key finder program
The first method to find the Windows XP product key is to use a key finder program. For this method to work, you need to install your copy of Windows on your computer using a stock key. Once Windows boots, you can follow the instructions below.
1. Download a key finder here
3. Run the program and click on the “Find Serial Number” button
4. The program will display the serial number on the screen
5. Write down this serial number

If you can’t find your serial key using the above method — or maybe you just don’t want to install a shady app on your PC — you can use a free Windows XP product key.
This method is simple, as you only need to scroll down and copy a serial key to proceed with the installation of Windows.
Do you need a Windows XP 32-bit or 64-bit key?
Should you use a serial key for Windows XP 32-bit or 64-bit edition? I know it’s a troubling question. Read the detailed answer below.
Windows XP was released for both 32-bit and 64-bit computers.
The bits (32 or 64) refer to your CPU’s architecture. If you have a 32-bit processor, you can only install a 32-bit operating system – Windows XP 32-bit, in this case. If you have a 64-bit processor, your CPU can handle a larger amount of memory and you should install the Windows XP 64-bit version.
When Windows XP launched, the majority of PCs were using 32-bit hardware. It meant that 90% of computers were equipped to run a 32-bit operating system at that time. However, you might have a 64-bit edition of Windows XP running on your PC.
To find out which version of Windows your computer is running, follow these steps.
1. Click on the Start button in Windows
2. Open System from the Start menu
3. Right-click on Computer and click on Properties
4. Now go to the System tab
