Safe Mode starts Windows with only the basic drivers and services it needs. If a problem goes away in Safe Mode, you know Windows itself is fine and the cause is a driver, an app or something that starts with Windows. It's also the place to remove a bad driver, a stubborn program or malware that blocks you in normal mode.
Windows 11 offers three versions:
| Option | Key | Use it when |
|---|---|---|
| Safe Mode | 4 or F4 | Most troubleshooting |
| Safe Mode with Networking | 5 or F5 | You need the internet (download a driver, run an online scan) |
| Safe Mode with Command Prompt | 6 or F6 | Advanced repairs from the command line |
BitLocker note: if your drive is encrypted, Windows may ask for the BitLocker recovery key. You can find it at aka.ms/myrecoverykey when signed in to your Microsoft account on another device.
Useful when you can't get to Settings, for example a black screen after sign-in.
If Windows fails to start twice in a row, it normally opens the recovery screen by itself on the next start. You can trigger this:
If the PC never reaches the recovery screen, you can start it from a Windows 11 installation USB drive and choose Repair your computer. Our guide to Windows that won't boot covers more options for PCs that don't start at all.
This makes the PC start in Safe Mode every time until you turn it off again, which is useful if you need several restarts.
msconfig and press Enter.Remember to undo it when you're done (see "How to Exit Safe Mode" below), or the PC will keep starting in Safe Mode.
You'll see a black background with "Safe Mode" in the corners and a low screen resolution. That's normal. Useful things to try:
Normally you just restart: Start > Power > Restart.
If the PC keeps returning to Safe Mode:
msconfig and press Enter.Older Windows versions opened the boot menu with F8. Windows 10 and 11 start too fast for that on most PCs, so Microsoft moved the options to the recovery screen described above. Some maker keys (such as F11 or F12 at power-on) open the maker's own recovery tools instead; check your PC's manual if you use those.
If the PC crashes or freezes even in Safe Mode, the cause may be hardware (drive, memory, overheating) or badly damaged Windows files. Back up what you can first, then check the drive and memory, or consider repairing or reinstalling Windows.
Pressing F8 at startup doesn't work on most Windows 11 PCs. Open the Startup Settings screen through Advanced startup, then press 4 or F4 for Safe Mode, 5 or F5 for Safe Mode with Networking, or 6 or F6 for Safe Mode with Command Prompt.
Turn the PC off during startup (when the logo appears) two or three times in a row. Windows then opens the recovery screen, where you choose Troubleshoot > Advanced options > Startup Settings > Restart.
Restart the PC normally. If it keeps starting in Safe Mode, press Windows + R, type msconfig, open the Boot tab, clear Safe boot, select OK and restart.
No. Safe Mode only starts Windows with a minimal set of drivers and services. Your files, apps and settings stay as they are.
