So I finally downloaded and installed the Raxco trial of this software... and it's amazing. I will be ordering a copy or two this afternoon. I looked at Rollback RX as well, but something about them giving discounts for writing testimonials made me uncomfortable. I couldn't help but doubt any good comments I saw about the program anywhere after seeing that. I've run into a couple of issues, but even with them, this software is too good to pass up: I tried to do a fresh install snapshot, following the instructions here: http://www.raxco.com/support/windows/kb_details.cfm?kbid=408 Everything went well with the install, and I was able to switch back to my other snapshots without problems. The issue came with my anchored data. I had anchored the My Documents folder under my username ("Normal"). When I went to My Documents in the new install, it was empty. I looked at the Documents and Settings and saw that there was now a folder for "Normal" and one for "Normal.CT" (CT is the computer name). My user in the new install had no permissions to access "Normal". The permissions for Normal listed an SID for having access rather than a username. Also, I seem to be having trouble with NOD and FDISR. I get errors when copying the active snapshot if AMON is not set to exclude the $ISR folder. The errors are Access Denied errors, and they are being triggered when ISR is attempting to copy some exe files (I know a couple of them are Office 2003 patches). If I exclude the folder, the copy works fine. I do have a "slower" computer, so maybe AMON just can't keep up with the copy process. My PC is a 866mhz PIII with 512mb ram.
