Document Windows Shift + Restart
You can get Windows to restart the PC on the Boot Menu:
-
Press and hold the Shift key while you select Power > Restart.
This should work in both Windows 8 and 10. I'm not sure about the small differences in Windows 8 but it's 4% of the Windows market share so let's forget about it:
| Version | Market share |
|---|---|
| Windows 10 | 63% |
| Windows 7 | 31% |
| Windows 8 | 4% |
| Windows XP | 2% |
