GoBack is much much much better. I can't think where to start....
All files are protected - SR only protects certain types like drivers etc
You can go back to virtually ANY time you want not just fixed Restore Points.
It operates from the boot menu should the worst happen!
I love it and wouldn't be without it.
Best feature is...
Add a note to the history as a marker.
Install a program
Don't like it? Crashes?? Doesn't work?? 2 easy steps to get back to the point before you installed it!!
However it completely rewinds the PC to that point! So if you installed program a and then program b then Goback to before you installed program a you loose both.
But it still allows you to recover EVERY single file that was "lost" when you rolled back. So if in between installing programs a and b you downloaded program c to your download folder but rolling back it would disappear (because you rolled back to before you downloaded it) but you easily recover the program c that you downloaded after you rolled back because GoBack keeps a copy of it! So you can recover it and not have to download it!!!
Its a real life saver.
