Safe mode

Safe Mode is a special way for Windows to load when there is a system-critical problem that interferes with the normal operation of Windows. The purpose of Safe Mode is to allow you to troubleshoot Windows and try to determine what is causing it to not function correctly. Once you have corrected the problem, then you can reboot and Windows will load normally.

Safe Mode starts up automatically if Windows does not boot on the previous attempt. You can also invoke Safe Mode by pressing F5 or by pressing F8 and selecting it from the boot menu.
