I'm finding this decision quite hard to decide on and can't decide what to do. I am very picky about wasted space or unnecessary stuff on my hard drive, yet I'd rather not install everything all over again which will take about 20 hours or so.
My question is...if I do an upgrade-install, can I just delete everything in the Windows.old folder and have everything practically the same as a clean install? Or will there be still be some left over things from the hundreds of programs I've installed and uninstalled?
I've ran the Windows 7 Upgrade Advisor and everything seems ok.
