If you have some issues in Windows 10 which you cannot resolve in the normal mode, there is a way to start it in the Safe mode. Safe mode is a special startup option designed for advanced troubleshooting.
Windows 10 inherited the boot options from Windows 8 and comes with the same graphical environment for various recovery related tasks. Due to this change, the Safe mode is hidden by default in favor of the automatic repair engine shipped with the new OS. If Windows 10 fails to boot, an automatic repair process will be started to fix startup problems on its own. You won't be prompted what actions it is going to take. Here is how to start Windows 10 in the Safe mode manually.
