Turn on system protection in Windows 8 and configure it

1. Click on Start, then on Search

2. Enter System into the Metro search

3. Now on the left side click on System Protection

4. Now select a hard drive at the bottom that you want to turn on system protection for. Then click the button Configure

5. Make sure to select the checkbox Turn on system protection

6. Now move the slider to the right/left to change the disk space that you want to give the system restore feature. This includes the disk space allocated for the “previous versions” / shadow copy feature.

If you have a lot of disk space, be generous here if you really want to use this feature. Personally, I am more relying on regular daily backups and backups of registry, important files, etc and the system file checker sfc.exe
