What’s Happening
Windows Recovery Environment (Windows RE) is a stripped-down OS that loads when your main Windows installation refuses to start—or when you need to tweak boot settings. It packs Startup Repair (an automatic fix for boot files), System Restore (a time-machine rollback), Command Prompt (for manual tweaks), and a handful of other utilities. Microsoft ditched the old F8 boot menu way back in Windows 8, so the Shift+Restart shortcut is now the standard way to reach these tools in Windows 10 (as of 2026, anyway).
Quick Fix Summary
Hold Shift while you pick Restart from the Start menu or the login screen. When the blue “Choose an option” screen pops up, select Troubleshoot → Advanced options → Startup Repair. In five to ten minutes, it runs a self-check and fixes most boot-time headaches—without touching your personal files.
Step-by-Step Solution
Open Settings → Update & Security → Recovery. On the right side, under “Advanced startup,” click Restart now. Your PC boots straight into Windows RE.
On the Choose an option screen, tap Troubleshoot (the blue tile).
Next, hit Advanced options.
Finally, choose Startup Repair. Windows runs a quick diagnostic and repairs any missing or damaged system files automatically. Give it five to ten minutes; if it fails, it usually spits out a helpful error.
If Startup Repair didn’t fix the problem, try these other recovery routes:
| Path | What it does | Time |
|---|---|---|
| Advanced options → System Restore | Rolls back system files, drivers, and registry to an earlier snapshot—your personal files stay untouched. | Two to five minutes |
| Advanced options → Command Prompt | Drops you into a full admin command line where you can run chkdsk /f, sfc /scannow, or bcdedit tweaks. |
Depends on the repair |
| Advanced options → Uninstall Updates | Rolls back the most recent monthly quality or feature update if the crash started right after an update landed. | Three to eight minutes |
