A questão
Leitor de superusuário Robith Nuriel Haq quer saber como impedir que outros usuários em seu computador desliguem:
I am using Windows 8.1 and have set up a child account for my son. When he wants to use the computer, I switch to his child account without signing out of mine (because I have a lot of open documents that I still work on and do not want to close them yet).
One day, when he finished using the computer, he shut it down immediately. When the computer shut down, I lost all of my open documents. It was a disaster. Is there a way to disable his account’s power button on the Charms Bar, or at least to prevent a shut down if other accounts are still logged on?
Existe uma maneira de Robith impedir que outras pessoas desliguem o computador para que todo o seu trabalho não seja perdido?

Solution
There are different ways to shut down the system, so you have to take that into account in order to avoid the issue entirely.
Preliminary steps
1. Make sure the user accounts you want to restrict are logged off.
2. Log on with an administrator account, and open an elevated command prompt.
Disable all shut down buttons and menus for a specific user
1. Type or paste the following command in the command prompt by replacing with the actual folder, then press Enter:
reg load “HKUUser” “%SystemDrive%UsersNTUSER.DAT”
2. Execute the commands below:
- reg add “HKUUserSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorer” /v “NoClose” /t REG_DWORD /d 1 /f
- reg unload “HKUUser”
3. Repeat steps 1-2 for any other user you want to limit.
Revoke shut down privileges assigned to standard users
1. Download the Windows Server 2003 Resource Kit Tools.
2. Extract the downloaded rktools.exe file using 7-Zip.
3. Open the folder containing the extracted files, and extract the rktools.msi using 7-Zip. Among all the files there is one called ntrights.exe.
4. Navigate to the folder containing ntrights.exe by running the commands below (after replacing the folder path inside quotes):
- cd /d “X:Somefolder”
- ntrights.exe -u Users -r SeShutdownPrivilege
- ntrights.exe -u Users -r SeRemoteShutdownPrivilege
Remove the shut down button on the logon screen
Execute this command:
reg add “HKLMSoftwareMicrosoftWindowsCurrentVersionPoliciesSystem” /v “ShutdownWithoutLogon” /t REG_DWORD /d 0 /f
