If the system restore feature in Windows 7 is not able to restore to a restore point, then you can start fresh and delete all your restore points. It is also needed in case of a malware infection to delete your restore points as the malware could have been present in those restore points. Here is how you can delete all of your restore points in Windows 7 :
- Press the key combination Windows logo key + R to open the Run dialog.
- Type SystemPropertiesProtection.exe in the Run dialog and press Enter. This would open the System Properties window, with the System Protection tab pre-selected.
- Select your system drive from the list (if you have more than one drives). The system drive has a windows icon on it and you would see (System) written next to it. My Windows 7 system drive is D:. For most of the users, it would be C:. Click on the Configure button.
- In the window that pops up, click on the button labeled Delete on the bottom-right as shown
- Click on the Continue button to delete the restore points in the confirmation dialog,
- You will see an information message box that all of your restore points were deleted successfully.
