boot to safe mode in windows 8 and windows 10 --- no luck with F8 key ?

You can still have Safe Mode, however, it is buried deep into the recovery options of Windows 8 or 10. While just mashing the F8 key as we all know will boot you into automatic recovery mode, you can still manually access the recovery options by pressing the Shift+F8 key combination. Even more simple, however, is the option to just hold the SHIFT key and click Restart at the login screen, or even within Windows.

Note: all of this should work exactly the same in Windows 10 as it does in Windows 8.
