Why do I keep getting a Genuine Windows Validation request?

Q  Recently, a friend recommended that I try Microsoft Pro Photo Tools. However, when I click the Continue button on this download page, my web browser seems to get transferred to something called Genuine Windows Validation.

I am guessing this is some kind of scam because I remember validating my copy of Windows XP years ago. So why is it appearing and how can I stop it so that I can download Pro Photo Tools?

A  In fact, this validation request is genuine but you’re not the first to write to us thinking it a scam – and we doubt you will be the last. In Microsoft’s defence, it does offer an explanation on the Genuine Windows Validation page but we know that it can be disconcerting to find yourself suddenly transferred from one web page to another that looks different.

It doesn’t help either that clicking the Continue button prompts the user to download a different file than the one they were perhaps expecting. Moreover, depending on the way your PC is configured, the GenuineCheck.exe file may prompt one or more security warnings to appear in Windows. So it is no wonder people worry about it.

However, proceed with the download of GenuineCheck.exe and then launch it and – assuming Microsoft determines that your copy of Windows is indeed legitimate – you will be presented with a small dialogue box bearing a short validation code.

Click the Copy to Clipboard button here and then use the Control (Ctrl) and V keyboard shortcut to paste it into the box provided on the Genuine Windows Validation web page.

Now click the orange Validate button and you will be returned to the previous page, where you will be free to proceed with your desired download.
