I get it, this is not my personal tech support team.
But I've googled my fucking fingers off and have arrived at asking in a thread.
Inherited an ex-school computer, the thing is it completely wipes clean every time I turn it off. Is there a way to reverse this kind of thing? I just want to be able to actually utilize this laptop.
Just pirate a copy of Windows 7 ultimate. Easiest shit ever.
Also try going into the BIOS settings and seeing if there's any options relating to wiping on restarts. Reset everything to defaults if possible.
Most helpful yet, will look into both of those. Thank you for your efforts gentlemen.
