I install windows Windows 7 by upgrading from vista; using Windows 7 upgrade.
It takes for one hour and a half, then completed.
I go to check disk space on C, then it appears 117 GB used
therefore I find out system requirement of windows seven. It is just 20 GB for x64
So I think the remaining must be some updated files or required space for Windows 7 themes.
But what exactly are they from and what is it?
and how can I hand it
please give me some information.
thank you very much
