Do you need a serial key to install Windows XP?

Yes, you do need a serial or a license key to install Windows XP. Before we get deep into it, there are basically three major types of Windows Licenses you will find as you are looking to get one for your system.

  • OEM (Original Equipment Manufacturer): These are known to be license keys that are sold with the internal hardware of the new computer that you purchase. They are available in CD format and are available only while you purchase a new system. Also, they are supported by the manufacturer of the system itself and not Microsoft.
  • Retail: The retail version is the one you get directly in a box from the stores or even from online e-commerce platforms. They have a little higher price than the OEM’s but are genuine and work alright with any of the systems you are working on.
  • Volume License: Such license keys are generally provided to large businesses where a single key is used for multiple systems at once and does not require any verification or activation too. The Volume License Keys (VLK) are the ones pirated the most and used by millions of users that you might find on the web for free.

No matter whether you are using a new system or an old one, you do need a serial key to get your system started.

Do you need a Windows XP 32-bit or 64-bit key?

A lot of newbies or users that might have just purchased a new Windows XP system do not have the idea of a 32-bit and 64-bit processor. Well, the only manner you can decide whether you should choose between a 32-bit or 64-bit key is if you are aware of your system’s architecture. It is pretty simple once you know what your computer works on.

If you have a 32-bit processor, it is recommended to go with the 32-bit key, and the same goes for the 64-bit processor. This will ensure the smooth running of the system rather than using the wrong keys based on the processor. You can check your system’s processor from the system settings and keep yourself updated.

How to Use Windows XP Home and Professional Product Keys?

There are multiple ways to do this. Since Microsoft has stopped all support for Windows XP, it becomes a little difficult for users to activate it directly using a genuine product key. One very easy method that might work for Windows XP Home is phone activation that might work for some and might not.

On the other hand, you might not need to activate the Professional product keys since it is a Volume Licensing agreement and as we discussed these keys do not require activation and would work after a simple installation.

  • Activate Windows XP via Phone

If you are looking to activate Windows after Microsoft has ended the support for any updates on Windows XP, here is how you can do it in the easiest manner.

    • Insert the installation disc and follow the guidelines for Windows XP.
    • In the Activation Windows, tap on “Yes, I want to telephone a Customer Service representative to activate Windows”, click on Next.
    • Wait for the system to Generate a New Installation ID
    • On the screen, choose the country in Step 1.
    • Now, call on the Toll-Free Number displayed on the monitor.
    • Provide the customer service representative the Installation ID written on the screen.
    • Once confirmed, the representative will give you a confirmation ID you need to enter on the boxes.
    • Tap on Next.
    • Now, click on Finish.

This process works like a charm and is much faster than the online activation method that might work provided the current scenario with the Windows XP support ended. You can use both Windows XP Home and Professional product keys to activate Windows in a similar fashion.
