Use Startup Repair when Windows will not start and the problem appears boot-related. Use System Restore when a recent driver, app, update, or settings change seems to have caused trouble and a suitable restore point is available. The tools address different problems: neither is guaranteed to fix every failure.
How Startup Repair and System Restore differ
| What to compare | Startup Repair | System Restore |
|---|---|---|
| Main job | Scans for and attempts to repair certain problems that prevent Windows from starting. | Returns system files, registry settings, and installed programs to the state represented by a selected restore point. |
| Best fit | Windows cannot boot normally and the issue may involve startup files or boot configuration. | A problem began after a system change, and a suitable restore point exists. |
| Personal files | Microsoft’s Startup Repair guidance does not describe the tool as a personal-file rollback. Back up important files before recovery when possible. | Microsoft says personal files are not affected, but system changes made after the restore point are undone. |
| Windows versions | Documented for Windows 10 and Windows 11. | Documented for Windows 10 and Windows 11. |
| WinRE route | Troubleshoot > Advanced options > Startup Repair. | Troubleshoot > Advanced options > System Restore. |
| Key limitation | Some recovery operations on encrypted devices may require the BitLocker recovery key. Startup Repair does not fix every startup failure. | A restore point must be available and suitable; later apps, drivers, updates, and settings may be affected. |
These options are documented in Microsoft’s Startup Repair, System Restore, Recovery options in Windows, and Windows recovery environment guidance.
When to use Startup Repair
Choose Startup Repair first if Windows will not start normally and you suspect a boot problem. From the Windows Recovery Environment (WinRE), select Troubleshoot > Advanced options > Startup Repair, follow the prompts, and restart when asked.
Microsoft says Startup Repair scans for startup problems and tries to fix them automatically. Examples include missing or damaged system files, corrupted boot configuration data (BCD), a damaged master boot record (MBR), incompatible drivers, and registry errors. These are problems it may attempt to repair, not a promise that it will resolve the cause.

When to use System Restore
Choose System Restore when the problem appeared after a recent system change, such as installing a driver, app, or update, or changing settings. In WinRE, select Troubleshoot > Advanced options > System Restore, choose a restore point from before the problem began, and follow the prompts. Microsoft also documents System Restore as an option when Windows is usable; the route and available screens can vary by version and device.
System Restore rolls system files, registry settings, and installed programs back to the chosen point. It does not affect personal files, according to Microsoft, but changes made after that point can be undone. Before applying a restore, use the option to scan for affected programs if it is available, so you can review apps and drivers that may be removed or restored.
Confirm that a useful restore point exists
System Restore only helps with the rollback you want if the available list includes a restore point from before the issue began. If there is no suitable point, this option cannot return the system to the desired earlier state.

Before starting recovery
- Back up important files when possible. Microsoft recommends backing up before recovery. System Restore is not a backup.
- Have the BitLocker recovery key available on an encrypted device. Microsoft notes that the key may be required for some recovery operations.
- Choose based on the symptom. A PC that will not boot points toward Startup Repair; a problem that followed a system change points toward System Restore, provided a suitable restore point exists.

If the built-in options are unavailable or do not resolve the problem, Microsoft’s next steps depend on the failure and your recovery setup. If Windows will not start and you do not have a recovery drive, Microsoft says you can create Windows installation media on a USB drive using another working PC. Treat that as a fallback rather than a requirement for running Startup Repair or System Restore. See Microsoft’s instructions for reinstalling Windows with installation media.
