I did it and yes no glitches until the few white screen crashes...but what I did was uninstall, clean the registry, delete any signs of the old install, then re-installed using the full installer of the latest rev...that was after doing virus/spyware sweeps using 4 different programs just to make sure. During the install process I disabled my anti-virus active scanning. The only thing I haven't done yet (and I should) is uninstall then reinstall my video and sound drivers.
