A restore point allows you to restore your Windows back to the state when the point was created. Any changes you make after creating a restore point are automatically undone as soon as the operating system is restored.

Restoring Windows 10 to a restore point is helpful when it gets infect with viruses or starts behaving obnoxiously due to multiple misconfigurations that can’t be rectified easily.

Creating your first restore point in Windows 10 might be a two-step process. If the Restore Point option is disabled in the System Protection tab of the System Properties box, you’re required to enable it before the OS allows you to create restore points.

Note: Restore point must be enabled for all the drives on your HDD/SDD individually. However, since it’s only C: that contains system files essential to run Windows properly, enabling restore point only for this drive should serve the purpose well.
Here’s how you can enable and create a restore point in your Windows 10 computer:

Step 1
Get to the System Protection tab

Type SYSTEM RESTORE in the Cortana search box, and press Enter. This opens the System Properties box with the System Protection tab selected. From here you can turn on/off and configure restore point settings.

Step 2
Turn on restore point

Select C: (System) from the Protection Settings list, click Configure, select the Turn on system protection radio button from the Restore Settings section on the next box, and click OK. This enables restore point for the C: drive on your computer, and takes you back to the previous box. Optionally you can use the slider under the Disk Space Usage section to manage the disk space reservation for the restore points. By default, 3% of the drive space is kept reserved.

Step 3
Create a restore point

Click Create from the bottom of the System Protection tab, type a name for the new restore point in the Create a restore point box, click Create, wait while the creation process completes, and click Close when it does. This creates a new restore point for your C: drive. Once created, any time Windows 10 starts behaving unexpectedly, you can come back to the System Protection tab, click the System Restore button, and follow the on-screen instructions to restore the OS to the restore point you created.
