I use bio mod and windows 7 was activated using Windows Loader. It hasn't given me any genuine error at all. Last week I upgrade it to SP1 and everything works fine.... until today. The "This computer is not running genuine Windows" pop up.. I try restore point but to my surprise there is no single restore point! I have no idea why as I reserved 500mb for them.. So now I have to fix it manually. I tried sfc/scannow but it say it has error. It doesn't seem to fix anything after reboot. I checked that those tampered files below are the same as those files in winsxs folder.. I have no idea why it say those files are tampered. Anyone know how to fix it?
