Safe mode is a special mode that starts Windows 11 in a basic state, using a limited set of files and drivers. It can help you troubleshoot problems on your PC by narrowing down the source of the issue. There are two versions of safe mode: Safe Mode and Safe Mode with Networking. Safe Mode with Networking adds the network drivers and services you'll need to access the internet and other computers on your network.
