How to Boot Into Safe Mode in Windows 11

What Safe Mode is and when you need it

Safe Mode is a diagnostic boot mode with a stripped-down driver set: generic display drivers, no startup programs, no third-party services, no unnecessary devices. Because the usual suspects never load, whatever misbehaves in normal mode often behaves in Safe Mode — and that alone tells you the problem is software, not hardware. Microsoft kept the mode for exactly these triage moments.

The classic use cases are removing malware that defends itself while Windows runs fully, and rolling back a graphics driver that black-screens your desktop. It is also the right place to uninstall an update that broke boot, or to delete a file some running process keeps locked.

• Removing stubborn malware that active protection shields from antivirus scans
• Rolling back a GPU driver that crashes or black-screens the desktop
• Uninstalling an update that broke boot or login
• Deleting a file a running process keeps locked
• Checking whether stutter or crashes come from third-party software, not Windows itself
• Running System Restore when normal mode fails before you can open it

Three ways to boot into Safe Mode from a working system

The Settings route: open Settings → System → Recovery, and next to Advanced startup click Restart now. The identical shortcut works from the sign-in screen or the Start menu's power button if you hold Shift while clicking Restart — and shutdown /r /o in any command prompt does the same. All three land you in the blue Choose-an-option menu.

From there pick Troubleshoot → Advanced options → Startup Settings → Restart. After one more reboot the numbered menu appears: 4 is plain Safe Mode, 5 is Safe Mode with Networking for when you need downloads or online fixes, 6 is Safe Mode with Command Prompt. Press the number once — no Enter needed — and a few seconds later the desktop appears with Safe Mode written in the corners.

When Windows will not start at all, and how to get back out

If the PC never reaches the desktop, force the recovery environment instead: interrupt boot three times in a row (power off the moment the manufacturer logo appears) and Windows enters Automatic Repair, which leads to the same Advanced options. Inside, Startup Settings works exactly as above; if you cannot get there even this way, you need recovery media — a bootable USB built on another PC.

One more route exists inside msconfig: the Safe boot checkbox on the Boot tab starts Safe Mode on every boot until you untick it — handy for repeated sessions, an easy way to get stuck if forgotten. Exiting Safe Mode is normally just a reboot. After you finish disinfecting, run a full scan in normal mode and sweep the junk the episode left behind: installers, quarantined files and logs pile up fast, and Kleaner PRO clears that residue in one pass.
