Back up important files
Before deeper system repair, copy irreplaceable documents and photos to a separate drive or trusted storage location. Confirm that the backup opens.
Install pending updates
Open Settings, review Windows Update, install available quality updates, and restart. Avoid interrupting an update once installation has begun.
Repair protected system files
Run System File Checker with sfc /scannow. If needed, repair the Windows component store with DISM, restart, and run SFC again.
Use Startup Repair when Windows will not start
From Windows Recovery Environment choose Troubleshoot, Advanced options, and Startup Repair. Do not choose Reset this PC until backups and less destructive recovery options have been considered.
Use System Restore for a recent failure
If a restore point exists from before the problem began, System Restore can reverse system and driver changes without intentionally deleting personal documents. Applications installed after the restore point may need reinstalling.
These steps provide general educational guidance and cannot guarantee a repair. Software cannot physically repair failed storage, damaged memory, overheating components, broken connectors, or liquid damage.
