It’s interesting to me that Windows Vista and Windows 8.0 didn’t stay long as No. 1. Probably because they were both duds.
I thought WIndows 7 was the most user-friendly windows.
Windows 7 is still my favorite OS.
My home computer is a Windows Vista (long story, there). These days I only use it for word processing.
And I will say one thing in defense of Vista. Using it is like participating in an exciting game of chance. It might do exactly what you want it to do. Or it might present you with blank windows when you expect something else.
Boot it up, and roll them dice!
