So yea... I tried upgrading the recently leaked 7264 build of windows 7 to rtm...
Visual Studio 2010
Microsoft Office 2010
Eset Nod32 Antivirus
Free Download Manager
Windows Live Mail.
Windows Live Messenger
so I run vista sp2 compatibility for it to install upgrade.
Copying Windows Files took 5 minutes.
I was like wow thats really fast.
Then it started gathering for file settings.
and sadly it took 6 hours (I'm Serious) after the first hour I went to sleep because it was like 12:30 am and I woke up like 6:20am and its was still gathering the files WTF?
but it was gathering files at the expanding windows installation part.
after like 30 minutes it finally finished.
and then finaly it was applying the gathered settings.
and it took another HOUR!...
at this point I was like UH OH.... even if this finishes it won't be stable or fast....
so it setup final finished.
It was like heaven when I saw the User Accounts from 7264...
I logged in my account.
and it was loading the desktop for like 5 minutes!....
but finally desktop shows up...
AND surprisingly everything was working and Windows 7 is snappier than before... and I'm just so happy it worked out fine LOL.
I guess I just got lucky? XD
