I have Windows 8 PRO 64 bit for 3-4 months.
At some point, Windows started to abandon system changes that I make, after Restart or after Shutdown+Start. It stopped saving my files associations. All the old associations are good, but all the new ones returns to the default ones, each time after restart. Also it abandons some other registry based data (I think), as the password of Goggle Drive (that I installed after this point), and Foxit Reader (that I installed after this point too) is always asking me to choose tabbed/classic interface, as if I've just installed it.
I didn't install any State Freezer software. I permit windows to update itself regullary. I have updated Eset Nod32 AV.
What could be the problem and how can I solve it?
