Dude , this issue mostly arises when you have a non-genuine Windows 7 installed on your PC and you use RemoveWAT to remove activation. The simplest method to resolve this issue is by removing RemoveWAT and let windows suspect you for counterfeiting. Then download and install WINDOWS 7 LOADER. It is a substitute for removeWAT but instead of removing Activation popups, it fools the PC into accepting OEM directories...gg Hope it helps..
