Get rid of the power and accessibility options on Windows 8 logon screen

Question

I'm using Windows 8 and I find the power button and the accessibility options very annoying. It's a computer that is in a public place surrounded with kids and they keep on changing the accessibility options and turn off the computer.

Is there a way to remove those two features from the logon screen and make it available for authenticated users only?

To remove the shutdown button:

Press the Windows Key, type gpedit.msc, press Enter.
In the Local Group Policy Editor, open Computer Configuration – Windows Settings – Security Settings – Local Policies – Security Options.
Find Shutdown: Allow system to be shut down without having to log on, double click it and select disabled – now the shutdown button will be gone.

To remove the Ease of Access button:

Press the Windows key and search for cmd.
Right click the Command Prompt result and select Run as administrator (click Yes when prompted).
Enter this command to forbid everyone to execute utilman.exe:

cacls %windir%\system32\utilman.exe /C /D Everyone
Type Y when you're prompted.

Should you be getting an Access Denied error, change the ownership of System32\Utilman.exe to Administrators (type explorer . in the command to open browser in current location), then try running the command again.

You can also take ownership on the command line:

 takeown.exe /A /F Utilman.exe

For Windows Home versions without Group Policy Editor, you can try the following, run regedit.exe as administrator and find or add the following REG_DWORD value:

 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\ShutdownWithoutLogon

a value of 1 means enabled, a value of 0 means disabled.

If the value ShutdownWithoutLogon is not there, just add it as a DWord 32-Bit value.

@Shimmy I paraphrased the instructions from the site Peter was linking to. We no longer allow links to it, since it's been spamming Super User quite heavily, and we don't want to feed any further traffic there. Hope you understand. – slhck Sep 10 '13 at 17:40
This also works for Windows 10. – Rosdi Apr 02 '16 at 03:48

Take ownership without Explorer: takeown.exe /A /F Utilman.exe – PollusB Nov 16 '16 at 04:27
gpedit.msc is unavailable in home version. Any way around it, without installing external software? – Shimmy Weitzhandler Jul 11 '17 at 20:22
@Shimmy - I added the registry change for the shutdown button. – Peter Hahndorf Jul 12 '17 at 03:45
@Shimmy There's a registry key for it which will likely need to be edited. I thought I had a bookmark that key was saved in, but I was wrong. Try googling something like: "Windows" AND "registry" AND "lockscreen" – JW0914 Jul 12 '17 at 04:45
@PeterHahndorf, thanks, the registry key did that. – Shimmy Weitzhandler Jul 13 '17 at 08:48
@PeterHahndorf I benefit your answer to this day, great answer, thank you Peter, you're awesome! – Shimmy Weitzhandler May 26 '19 at 05:19
You must change Everyone to the localized name of this group on non-English versions (e.g. Todos in Spanish). Anyway, you only need to deny access to SYSTEM. This way, the button doesn't work in lock screen but it does for users. – cdlvcdlv Aug 28 '19 at 22:09
Hi, this answer is great, I'd also like to remove the network flight mode button. – Shimmy Weitzhandler Jun 24 '20 at 15:06
