hi Felipe.U can just do factory reset on windows.It takes looong time and it remove viruses…. But if u cant get into windows then its different case… 😀 That other method I wrote about, I used when screwed with factory reset and did work for me. After 1.5 hour of waiting for tablet response, I turned it off and all restoring process went into ass. So there was no other way just to restore whole windows partition with previously written method. It didn’t delete activation key and didn’t screw android either. If your android is fine, don’t do anything with android installation. Just concentrate on windows and everything will be ok. It is not necessary to use exactly same size of usb sticks like I described, use with enough memory. One thing thou, after installation you’ll need remove password request after save screen, or else every time you tablet awaking from standby, touchscreen will not work until u use usb keyboard. Somebody suggested format whole system and install just windows but I don’t know is it possible. So if anyone knows more about touchscreen going off after putting tablet in standby mode, please give some info 😀
