Safe mode

(Redirected from Safe Mode)

Safe mode is a diagnostic mode used by computer operating systems to troubleshoot problems that cannot be fixed while running in normal mode. In safe mode, the operating system loads only the necessary (minimal) drivers and software so that other problems can be found and repaired.

Safe mode on a PC should be used when doing a full system virus scan using Windows Defender, MalwareBytes, or similar antivirus software, to ensure that the scan is most effective.

Safe mode is also useful for both Mac and PC if there is some type of hardware problem that causes the machine to not boot properly, or freeze during operation.
