I use Terabyte products for backup (Image for Windows/Linux), but am having a particular problem where if I execute a certain function within an application, it gets corrupted. My only fix has been to do a full restore of my PC each time it happens. It's very time consuming. There are about a dozen switches and levers I can test to figure out the problem, but I'd like a quicker way of restoring to a moment in time. Is there a free or cheap rollback software where I can put everything back that changed within a few minutes time? I know this might be a common question here, but I've never used rollback software before. It can't be done within a virtualbox or Vmware snapshot. This has to be on my particular live PC.
