How to Remove This Copy of Windows That Did Not Pass Genuine Validation

When installing a copy of the Windows operating system, you are prompted to enter the "validation code," at which point you will learn whether your version is viable. If you have a copy of Windows that is not genuine or tried to install one that has already been validated by another computer, thus making that copy ineligible for updates, you can remove this copy of the operating system.

Step

Start up your computer. If you see the "Genuine Validation" prompt, this copy of Windows will need to be removed.

Step

Restart the computer in Safe Mode by holding down the "F8" key while the computer reboots. At the boot menu screen, read all the options carefully, as they will be in a slightly different order for different versions of Windows. Select the "Safe Mode" option by scrolling up and down with the arrow and "Enter" keys.

Step

Allow the computer to boot up fully after selecting Safe Mode. Click the "Start" menu button and select "Control Panel button." Click the "Add/Remove Programs" icon.

Step

Allow the program list to populate (this may take a few minutes). Search for the version of Windows installed on your computer and select it from the list by clicking on it. Click the "Remove" button to the right of the highlighted selection. Wait for the "Are you sure you want to uninstall Windows" prompt to appear and then select "Yes." Allow the computer several minutes to completely uninstall Windows.
