How to Activate Windows XP Without a Product Key

Did you just install, or reinstall Windows XP on your Computer, and when you are trying to activate the software, Microsoft says that your product key is not genuine, the product is no longer available for retail sale, or the number of activations have been exceeded? It may ask you to call Microsoft to get a new product key, or purchase windows 7.



Instead of going to this trouble, or instead of spending hundreds of dollars, to get a new genuine product, here is a way to make your product activated Without a Product Key.

Click on Start

Find and Click "Run"

Type: regedit

Click the plus next to "HKEY_LOCAL_MACHINE"

Click the plus next to "SOFTWARE"

Click the plus next to "Microsoft"

Click the plus next to "Windows NT"

Click the plus next to "CurrentVersion"

Click "WPAEvents"

On the right panel, find "OOBETimer" then double click it.

Now, highlight all values, then delete them

Then type in the following value : FF D5 71 D6 8B 6A 8D 6F D5 33 93 FD

After that, click 'OK'.

Next, on the left panel, right-click WPAEvents, and then click on "permissions"

Click "System" or "SYSTEM", then click the box "Deny Full Control", and then click 'Apply'.

Now you can exit the Registry Editor by clicking on the red X in the upper-right corner of the Title Bar or, while holding down the ALT key, press the F4 key.

To verify that it works, Click on Start, then "Activate windows", or click on Start, then All Programs, then "Activate windows"

If it says that Windows has been activated, then the trick works.
