Unlike most of the registry hacks on this site, we didn’t come up with this one! In fact, it was Leo Davidson who figured it out and wrote the easy fixer utility, and Ed Bott, author of the excellent Windows 7 Inside Out book who pointed us towards the fix. You should subscribe to their sites, and buy Ed’s book! (seriously, it’s an excellent book)
