Windows release has a pattern.
Good, Bad , Good , Bad ….

Let’s see the past release.

Windows 2000 Good
Windows ME Bad
Windows XP Good
Windows Vista Bad
Windows 7 Good
Windows 8(include 8.1) Bad
Windows 10 Good?

Actually ,I bought all Windows version.
But Windows ME and Vista and 8 are rarely used in my case.

But I think Windows 10 will be success!
So I installed it on my PC for experiment.

It took one hour to finish install.

Caution:
Microsoft doesn’t provide Japanese version.
Please install it at your own risk.
