Welcome herb milich,
Thanks for reaching out to Microsoft Q&A Forum. I understand that the Power button in your Windows 11 Start menu only shows Lock, and you want Restart, Shut down and the other options back.
To narrow this down, could you please confirm:
- Did this start after a Windows update, or after you installed a Start menu customization, privacy or tweaking tool?
- If you sign in with a different user account on this PC, does that account also show only Lock?
Please make sure you already tried the Q&A Assist steps. In addition, please try the following:
1, Restart the PC using the Run box
- Press Windows key + R, type shutdown /r /t 0, then select OK.
- The PC restarts right away, so save any open work first.
2, Check the machine-wide policy key in Registry Editor (back up the key before you change it)
- Press Windows key + R, type regedit, then select OK and approve the prompt.
- Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer
- If you see NoClose with a value of 1, change it to 0 or delete it.
3, Check for connected work or school accounts
- Open Settings > Accounts > Access work or school.
- If you see an account or organization you don't recognize or no longer use, select it and choose Disconnect. It may be pushing policies to this PC.
4, Revert or remove customization tools
- If you use a tool such as Winaero Tweaker, O&O ShutUp10++, ExplorerPatcher or a similar app, open it and restore its default settings, or uninstall it from Settings > Apps > Installed apps.
Looking forward to your update.
