Hey there!
Nice to meet you! I'm Randy, an Independent Advisor.
Hi, System Restore in Windows doesn’t touch your activation status, so it won’t restore or undo your Windows Product Activation. If your system is already activated, using a restore point won’t deactivate it, and if it wasn’t activated before, restoring won’t suddenly fix that either. It just focuses on system files, drivers, and settings not license data.
Best regards,
