Turn on System Protection so Windows can make restore points

1. 1

   Open System Protection

   Open Start, type Create a restore point and open it. Windows opens System Properties on the System Protection tab. Or press Windows key + R, type SystemPropertiesProtection and press Enter.

2. 2

   Select your system drive

   Under Protection Settings, select the drive marked (System), usually Local Disk (C:). If its Protection column says Off, go on.

3. 3

   Turn on system protection

   Select Configure, then Turn on system protection. Max Usage sets how much disk space restore points may take. Select OK.

4. 4

   Make a restore point

   Back on the tab, select Create, type a name and select Create. Or use the Make a restore point button in Frozen Tweaks, which every plan has.

Yes. Open PowerShell as administrator and turn System Protection on for C: with:

Enable-ComputerRestore -Drive "C:\"

Then make a restore point with:

Checkpoint-Computer -Description "Before tweaks" -RestorePointType MODIFY_SETTINGS

Both are Microsoft's own commands, documented on Microsoft Learn (sources below).

Windows lets programs make one restore point every 24 hours. Microsoft documents this for Checkpoint-Computer: a new restore point within 24 hours of the last one is refused. If you made one earlier today, that one is your way back: rolling back to it also undoes the system changes made after it.

Single tweaks don't need one: every free tweak has an undo switch in the app. The restore point is the way back from the Pro one-click run. The run makes one before it changes anything, checks that it exists and stops if Windows can't make one, so System Protection has to be on.

Undo a tweak or roll back the run shows how to go back. The FAQ explains what the run changes in Windows Security.
