Microsoft has tried a few different anti piracy measures to protect Windows over the years.
In XP that protection is called Windows Genuine Advantage and gets downloaded during a Windows Update session.
mu Blinder is a small portable tool that helps you bypass Microsoft Update’s Genuine Windows Validation.
Have you ever been in the annoying situation that you try to update your Windows XP using Microsoft Update only to discover that for some reason it’s not classing your Windows as genuine?It’s not really clear how or why this can happen, but is likely to be one of the WGA files that has got corrupted.Notification is the component that will turn your desktop background black and place a watermark in the bottom right saying your Windows is not genuine.You will also have a system tray icon pointing you to the web and the “virtues” of owning a legitimate copy of Windows.WGA Validation is the component that will install when you go to Windows / Microsoft Update.
If your install fails validation, this will stop you updating a number of different updates including non critical ones like Windows Media Player, Internet Explorer, Windows Defender and Security Essentials.In actual fact, there are two versions of the Windows Genuine Advantage (WGA) protection.They are called Notification and Validation and are separate components in that they do different things on your computer.I’d recommend you try the first set of instructions to begin with, the second set is provided in case you can’t get the first working.There are also a few applications that will attempt to remove WGA for you (more on those later).Click the Enable button and mu Blinder replaces the DLL with a patched version to allow updates.
