Goal: Safe Mode starts Windows with a reduced set of drivers and services so you can determine whether a problem is caused by normal startup software, a driver, or another component loaded in a full Windows session. This guide shows the supported ways to enter Safe Mode, what the different variants mean, how to diagnose problems methodically, and how to avoid configuring the PC to loop into Safe Mode. Quick steps If Windows still opens, go to Settings > System > Recovery > Advanced startup and choose Restart now. In Windows Recovery Environment, choose Troubleshoot > Advanced options > Startup Settings > Restart. Choose Safe Mode, Safe Mode with Networking, or Safe Mode with Command Prompt according to the test you need. Reproduce the original problem without making several changes at once. Restart normally after testing. Expected result: Windows reaches a reduced diagnostic session and a normal restart returns the PC to standard mode.
