How to turn off System Restore and remove System Volume Information folders in Windows?
There's a way simpler solution than the former answers regarding deleting the directory.
It's actually in the same place where you disable the protection.
- Press Win+Pause or Start Button → System Preferences → System
- Left Pane → System Protection
- Mark the volume you are working on, and then hit Configure
- In the dialog popping up, hit the delete button and confirm. It basically deletes all Windows Restore Points, nothing else.
After that the System Volume Information Directory is empty and you can do whatever you want.
You don't even need to disable the System protection on that drive. The Directory will be emptied anyway.
