Configure System Restore to Use Less Space

System Restore is an integral part of the Windows Operating System. It allows you to roll-back your system files, registry keys and installed programs. If you install a bad driver you can revert the registry back to when the system was running fine. If you get a virus, you can revert the registry back to before the times when you were infected. So System Restore is an invaluable component of  Microsoft Windows. But if you’re not careful, it can devour your C: drive, consuming all empty space you have.

Change System Restore Allotted Space

If you want to restrict System Restore to use only an certain amount of allotted space in Windows 7, you can do so by going to Start and right-clicking My Computer. Select Properties, then in the left column choose System Protection.

Next, click the Configure button.You can then configure how System Restore behaves by changing the settings. You have the option to Restore system settings and previous versions of files, only restore previous versions of files, and turn off system protection altogether.

Below those settings you will see the option to control how much space System Restore is allowed to use. As space fills up, older restore points will be automatically removed. This is usually completely fine if you know you have good restore points. If you do not keep an eye on this setting, you may find the empty space on your C Drive is slowly consumed.

It is recommended that you leave this alone unless you find a need to change it. System Restore can save you when you least expect it, and with the size of modern hard drives, you may find you never need to change this setting at all. Just be aware of it if you find your C drive space getting dangerously low.
