I'm trying to investigate the various imaging and rollback programs and there seem to be a few "Shadow" variants which doesn't help trying to remember which one is which! Now if I am right ShadowProtect is like Acronis TrueImage, useful for imaging and restoring entire partition or disks and restoring whole thing. Shadow User (from same company as above?) and Shadow Defender seem to be more virtualization programs? What are the differences between these two? They both seem to do the same thing. How do they compare to something like Deep Freeze and Rollback RX? All seem to have the ability to freeze a system while allowing certain folders and zones to be left unfrozen. Though I'm not sure about Deep Freeze allowing individual folders to remain unfrozen? Any others to be aware of which fall into the category these last few ones seem to fall into?
