It's worth a try, but make sure you have a standard restore point, or better still a full backup before you start. I must say I quite liked it, and I am not sure that it was the cause of my problems but I have Acronis Nonstop Backup so I haven't tried it again.
I had major issues with this program. It installed and ran OK buy I decided that it was not for me so,rather than uninstall,which in hindsight I should have done,I just used Acronis to wind the clock back a couple of hours.
System would not reboot,in normal or safe mode or off the Acronis boot disk, - "hal.dll missing or corrupt" ...... and I had to reinstall Windows in order to get my Acronis to restore its image file.
CTM obviously makes major changes to the booting of the system and I would hope that running the programs own uninstaller would reverse those changes.
Despite my enthusiasticnerss in Rawprawn's link, I have had to un-installer it from my vista based machine. It caused lots of problems when resetting the baseline. Had to resort to backup to restore my machine.
That said, on my XP machine it is running like a charm.
I would take Rawprawn's advice and do a backup first, then try it out. You can always restore your backup afterwards if things go pear shaped.
I understand it is best to un-install it from the flash screen at system startup.
