Hey,
I had done this about 2 months back. But yesterday after using my pc for a while, I switched accounts. On logging in, the windows not genuine thingy came up in the corner. I was using microsoft security essentials for quite a while, but now I will not able to as it says windows did not pass validation.
What caused this? How can i get back validation? Thanks..
