I made a mistake and installed 4.0b RC 1 over the regular 4.0 SR3 on my main machine. No crashes so far, but it was downloading and indexing for the last 10 hours. Anyway, I don't want to keep the beta on my main machine and am prepared to re-install whatever "gold" version comes next.
At this point I need instructions on how to wipe all traces of 4.0b RC 1 from my computer.
