How Windows recovery tools, firmware settings, drivers, system-file repair, and reset options apply to different failure layers.
Choose a Windows repair tool according to the affected layer, starting with the least disruptive option.
| Failure layer | First tools |
|---|---|
| Startup applications or services | Task Manager startup controls, Safe Mode, msconfig |
| Driver behavior | Device Manager, driver update or rollback |
| System-file integrity | DISM and sfc |
| Disk or volume state | Disk Management, diskpart, chkdsk |
| Startup blocked | Windows Recovery Environment (WinRE), Startup Repair, System Restore |
WinRE is a recovery environment for cases where normal startup or in-session tools are unavailable. Reset or reinstallation should follow backup, compatibility, and lower-impact repair checks.
