Choose a Windows recovery starting point from boot status, backup, encryption, and device ownership. This tool never runs a repair or reset.
Protect your files first
Back up important files when possible. If the drive is encrypted, locate the BitLocker recovery key before recovery changes. Stop if storage appears to be failing or this is a work or school managed PC.
Use the tool
How to interpret the result
Startup Repair, System Restore, and Uninstall Updates have different effects. Reset and reinstall are not automatic recommendations.
Protect your data
This tool reads the values you enter in your browser. It does not connect to your PC, execute a command, upload a dump, or collect a recovery key. Keep passwords, product keys, and serial numbers out of public search fields.
