I have sony vaio laptop come with window 7 home basic.Laptop showing problem while running some programs.I want a fresh installation of window 7 home basic but no window 7 disk come with laptop.
Should i download window 7 home basic ISO file from Microsoft website and activate it with the key written on the bottem of the laptop.I want to know will it work.
