I've think about the Windows 10 upgrade update. 1.Will be there a '''pre system check'' if the current pc system can handle Windows 10? eg you have a machine that runs 7 with a P4 cpu . will it be warn you that you CANNOT UPGADE? 2.Is there a software compatibility check ? Because when someone has an old cpu and it CANT HANDLE IT, and he upgrade it from 7 to 10 and it goes wrong wil he lose his files? Is Microsoft thinking about this? yes or no?
