LKGF doesn't restore HKEY_CLASSES_ROOT. I learned that two weeks ago writing the program that puts icons on all desktops even when folder redirection is in use. I accidentally hit Del at HKCR\CLSID. Oops! As for rollback, if you use VMWare GSX to deploy your production machines as guest operating systems, rollback is one mouse click. It makes backup/restore/duplication of machines a snap. I haven't done it in production yet, but I built an AD/Exchange sandbox to test a domain/Exchange migration and it was awesome. After installing the host OS on a Dell 2650, I got 4 guest OS's up in about an hour, and most of that was building the first one. I realize that this information probably doesn't help you now, but it's something to consider for the future.
