Vista to Windows 7 - Upgrading or clean installation?
Should I upgrade my Windows Vista to Windows 7 or wipe/format/install Windows 7?
I have a Dell Precision T3400 workstation that came with Windows Vista and a few months later Dell shipped me a Windows 7 upgrade (for free). I have yet to upgrade it and as it's inconvenient to backup/format/install Windows 7. The question is, should I just upgrade directly without a format?
I don't know if this is a proper question, or if it even can be one, but I need details on experiences with upgrading. I have never done this before, but Win Vista --> Win 7 doesn't seem like an upgrade with lots of pitfalls.
