Hello Friends,
In this time window 10 is launched but compare Windows 7 and Windows 10 I can't say anything because both windows are by Microsoft and both Windows are good. Some windows run properly in some pc or computer but some lacked.
It is depend on your system stability. 2 years ago I used window 7 and now I used windows 10.
I like both the windows very much.
1- you can change windows 10 to windows 7 or windows 7 to windows 10.
