Windows 10: Sleep option gone missing

I can't seem to choose the sleep option in power settings or the control panel power options. It just suddenly disappeared from everywhere.I have tried every method to fix it from researching the internet. From cmd prompts to local group policy editor and whatnot.

Computer Sleep Option Missing in Settings

The Settings Power and Sleep menu in Settings should list Screen and Sleep, where Sleep is used to tell when the PC goes to sleep. Sleep is missing, so my computer never sleeps. Fast startup and Hibernate are not enabled. I used Tutorial Add or Remove Sleep in Power menu in Windows 10 to change the registry while in administrative mode, but sleep still is not seen. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FlyoutMenuSettings now lists :1: It was 0 before the change.

I cannot get a large image, so will type Default REG_SZ (value not set) ShowHibernate REG_DWORD 0X00000000 (0) ShowLockOption REG_DWORD 0X00000000 (1) ShowLockOption REG_DWORD 0X00000000 (1) I used Option 3 to add sleep using the Group Policy Editor. The steps seemed to work fine, but sleep is still missing. I’m using a “new” refurbished Dell T3500 workstation with mbr running the current version of win10. I have a number of these computers, and the other all have the normal sleep mode . Any suggestions? Jim

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

Sleep option is missing

Windows 10 HOME, build 16299.192

Sleep option is missing under Power Options.
I might be able to fix the doing a system image restore. But would like to know if there is a better way.
