Quick answer: You can delete restore points, but you lose rollback options for recent system changes.
Why this uses C drive space
Restore points can recover from bad drivers, updates, and settings changes. Deleting them is a tradeoff, not simple junk cleanup.
Safe cleanup steps
- Confirm Windows is stable.
- Back up important files.
- Open System Protection settings.
- Delete old restore points from Configure.
- Create a fresh restore point afterward if protection remains on.
What to avoid
Do not delete restore points right before driver updates, Windows upgrades, or risky system changes.
