A few weeks ago my laptop got fixed and this dude upgraded it to a Vista premium. & when I logged in yesterday a windows acivation box came up, i tried typing in the product key that was on the bottom of the laptop but it didnt work , so i tried things of the internet to find the right product key but that still didnt work.
so i tried validating it and it was going okay til it said validate windows, and when i tried to right click computer for properties or go on computer and click system properties it wouldnt do ANYTHING at all.
Is there anything I can do? I cant be doing with logging off every hour.
