Hi, I want to upgrade pretty much my entire system except for my video card and my hard drives, mouse and keyboard. I read somewhere that someone did this, they booted into safe mode, removed all the drivers, upgraded and windows loaded fine, and operated fine.
I have not tried this with Win7, but for WinXP, a "repair install" worked the 2 times I tried it.
But I'm thinking about the sysprep tools that MS offers. They can remove any system-specific settings, but I don't know about user settings (by default user profiles are also removed).
Has anyone here changed motherboards without re-installing windows? Can you comment on the slow-own this can cause?
If changing the entire system, I would recommend a clean re-install of the OS. I don't think it'll cause slowdowns, but it might cause some or a lot of files to go corrupt. So just backup important files and then do a reformat.
