System Restore has been a key recovery feature in Windows for years. With this free built-in tool, you create snapshots that preserve the current state of your Windows environment. If a problem arises that impacts specific applications, settings, or Windows itself, you can revert your PC to a previous restore point before the problem occurred.

Though System Restore may be an old feature, it's still as effective as ever.

System Restore saves the current state of your Windows system files, Registry settings, device drivers, and installed programs. It doesn't capture your personal files, so you can't use it to recover lost documents, photos, emails, or other content. For that reason, it can't serve as a full backup tool, but rather as a way to undo system changes when other troubleshooting methods can't fix a Windows problem.

Windows automatically creates system restore points at key moments. A restore point may be generated before you install certain applications, install a major Windows update, install new device drivers, or make specific configuration changes. Windows will also create a restore point every seven days if no points have been generated during that time.

But you can and should manually create restore points at other times, especially if Windows doesn't necessarily generate them on its own. I typically create one before any significant changes, including new applications, new device drivers, or tweaks to core Windows features and settings. Since I do fiddle with Windows a lot, these restore points are a valuable resource when something goes awry.

System restore points naturally use up space on your hard drive. But you're able to control how much room to devote to them. When the allocated space fills up, the oldest restore point is deleted to allow storage for newer points.

Now, here's how I use System Restore on my Windows 11 PC and how you can do the same.

To set up System Restore for the first time, head to Settings, select System, and then click About. In the Related links section, click the link for System protection. In the System Properties window, click Configure.
