Safe Mode is most commonly used to diagnose if a problem on a computer is being caused by a third-party element such as a third-party application or a service/process that is part of a third-party application. Normally, Safe Mode doesn’t even have network access or the ability to open a Command Prompt unless a user specifies that they want network access and/or the ability to open a Command Prompt in Safe Mode while they are booting their computer into Safe Mode in the first place. What Safe Mode does is quite simple – when a Windows computer starts in Safe Mode, the computer is started with only stock applications and services running – everything that wasn’t on the computer when Windows was installed is disabled. Safe Mode has been a constant throughout the many different iterations and versions of Windows that have been developed and distributed – any computer running on Windows has Safe Mode built into it.

Safe Mode is a diagnostics utility built into the Windows Operating System.
