>My guess, Win 7 had UAC turned off and you didn't hit the instances where you still have to elevate.

So, basically, if one would turn UAC off, that should resolve most of the issues.

IAC, I will see how it works as I put all the data on D: drive. So, I hope whatever I will install, SQL Server, IIS, Office, .NET and such won't be blocked to be installed on C: because of this UAC.

Thanks for helping me on this.
