Ruined Login Screen

Even though it can be reverted back easily, it might be better to disable this button on the lock screen. Please note that this trick works on all Windows versions, including Windows 10!

So let's get started by taking ownership of the Utilman.exe file located in the System32 folder.

Start by bringing up a command prompt in administrator mode, and use the following command to get permissions

takeown /f C:\Windows\System32\Utilman.exe

You should get a confirming message claiming that the executable is now owned by your user account. Great, now let's fiddle around with the executable and it's permissions. Navigate to the System32 folder and locate the Utilman executable file. Right click on it, and click on properties. You should get this window

Utilman.exe properties window

Click on the Security tab, click on the SYSTEM user in the upper list, and then click on the Edit button.
Read and Read & Execute rights should be disabled like this

Utilman.exe permissions

Click on Apply and you should be good to go!
