Enable System Protection for Disks on Windows 11

You may know that creating a restore point is a good practice, but what you may not know is that Windows can automatically create them for you too. This is through a feature known as System Security. But what is it and how do you turn it on when it’s off?

Here’s what you need to know.

What is System Security on Windows?

System protection is a feature that creates restore points on a particular drive when changes are detected.

However, not every change leads to system security. The scenarios in which System Protection automatically creates a restore point include when an app it recognizes makes a change to Windows or a Windows update is installed.

The restore points created by System Protection are stored on disks on your computer with the feature enabled. By default, Windows manages how much disk space is allocated to the restore points when the System Protection feature is enabled, which is usually between 1% and 5%. The system will try to keep this space below 10 GB. That means if you have a 1TB drive, it will allocate about 1%, and if it’s 256GB, that’s about 4%.

And when the restore points get full, old ones are deleted and replaced with new ones. However, there is a way to manually allocate more disk space for restore points (more on this later).

System protection is enabled by default, but if it isn’t, you can easily enable it in two ways.

1. Enable System Protection for Disks in Settings

You can easily enable System Protection for Drives in the Settings app by following the steps below:

  1. Press Win + I to open the Settings app.
  2. Navigate to System > About and click on the System security clutch.
  3. In the Security Settings part of the System properties window, you will see a list of available drives. If a disk has System Protection not enabled, it will say: Out next to it. Select the drive you want to enable protection for and click Configure.
  4. Another window will appear. Check the Enable System Security radial button.
  5. You can also use the Maximum usage slider to the right to allocate more disk space for saving restore points. And if you want to delete all restore points on the drive, click remove.
  6. When you’re done, click Okay to close the window and save the changes.

Now the drive has System Protection enabled. If you want to disable it, just follow the steps above, but when you get to step 4, check the Disable System Protection radial knob instead.

2. Enable System Protection for Disks in PowerShell

You can also enable System Protection using PowerShell. To do this, follow the steps below:

  1. Press Win + S to open Windows Search and type power shell in the search box.
  2. In the right pane of the search results, click Open as administrator below Windows PowerShell.
  3. Click Yes at the UAC prompt.
  4. In our example, we would enable System Protection for the drive letter C. So in PowerShell we entered the command below:
    Enable-ComputerRestore -Drive "C:"

    Feel free to replace C in the above command with the drive letter of your choice.

  5. Touch Enter on your keyboard to execute the command.

The System Protection feature will now be enabled on that drive.

If we wanted to disable System Protection with PowerShell, we would enter the command below in step four above:

Disable-ComputerRestore -Drive "C:"

Press on the Enter key to execute the command, and the disk is no longer protected.

Enabling system protection is the best way to protect your computer

As great as it is that Windows allows you to make changes to improve your experience, things can go wrong. System Protection is your backup plan in case changes you’ve made backfire. With the restore points it creates, enabling at least one of your drives is a great option, even if you don’t think you need it right away.
