Start is missing hibernate, sleep, lock options

The visibility of the hibernate, sleep, and lock options are usually controlled by: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FlyoutMenuSettings

Open

If the registry keys are not initially there, you can use the following to add them:

"ShowSleepOption"=dword:00000001
"ShowHibernateOption"=dword:00000001
"ShowLockOption"=dword:00000001

Again, log out \ in for the change to take effect
