Safe mode starts Windows in a basic state, using a limited set of files and drivers. If a problem does not happen in safe mode, this means that the default settings and basic device drivers are not causing the issue. Observing Windows in safe mode enables you to narrow down the source of a problem, and can help you troubleshoot problems on your computer.
Safe Mode: In safe mode, Windows has reduced functionality. The task of isolating problems is easier since many non-essential components are disabled, such as sound, third-party drivers and services, non-essential Windows services, and more. Corrupt software, drivers, or the installation of poorly-configured software prevents Windows from successfully booting into normal mode.
Safe Mode with Networking: In safe mode with Networking, you have the same environment as Safe Mode, but includes network drivers. This lets you connect to the Internet and network devices for downloading updates, drivers, and patches, or for remote help.
