What is Safe Mode?

Updated September 12, 2026

If you have worked with Windows for any length of time you are probably familiar with the term “safe mode.” You might have heard of it, but do you know what it is?

Safe Mode is a diagnostic startup option in Windows and other operating systems. It loads Windows with a limited set of drivers and services so you can narrow down a problem. If a crash does not occur in Safe Mode, a startup app, driver, or service that does not load there may be involved; that result alone does not identify the cause.

If the problem also occurs in Safe Mode, the cause needs further investigation; it could involve Windows, hardware, or another component that is still active. Safe Mode is for troubleshooting, not everyday use. The Safe Mode with Networking option enables network drivers and services when you need them, but connectivity is not guaranteed in every situation.

On Windows 11, open Settings > System > Recovery > Advanced startup > Restart now. You can also hold Shift while selecting Power > Restart. In the Windows Recovery Environment, choose Troubleshoot > Advanced options > Startup Settings > Restart, then select Safe Mode or Safe Mode with Networking. If Windows cannot start normally, it may enter recovery automatically after repeated failed starts. Some recovery options may require your BitLocker recovery key. Do not rely on F8 working on a modern PC.

When you are in Safe Mode, you can do several things to help resolve whatever issues you are seeing. These tasks include:

· Scan for Malware

· Run a System Restore

· Uninstall Software

· Update Hardware Drivers

· Check if a certain behavior, such as a crash continues to happen

Safe Mode can help identify a problem, but a reset or reinstall may sometimes be appropriate. Windows' Reset this PC feature may offer a Keep my files option, but it removes installed apps and can change settings. Back up your important files before resetting or reinstalling Windows; no recovery option should be treated as a substitute for a backup.

If Windows needs to be reinstalled or reset, you may have to reinstall applications and restore settings afterward. Keep a record of the software you use and store any required licenses or product keys somewhere you can access even if the computer will not start. Keep backups in a secure location or a trusted cloud service, and confirm you can restore them.

Safe Mode is a useful troubleshooting tool, but persistent crashes, suspected malware, or recovery problems can take experience to diagnose. If you need help, Unfrustrating Computers can assess the problem and help you protect your files before repair or reinstallation.
