Win XP/SP3 32-bit - I just attempted to restore a differential backup with Paragon Back & Recovery Free. The process was successful, however, when I restarted my computer, I noticed that the restore was, in fact, not successful. Configurations, such as my desktop resolution were changed, and my Quick Launch shortcuts were gone. Additionally, programs, such as Comodo Firewall stopped functioning (Comodo reported errors). I decided to restart the computer, and it booted into a screen which is flooding "Replacing invalid security id with a valid security id." Edit: I'm back into Windows XP and the entire taskbar is missing. Additionally, I have about half the amount of processes running now.
