I have a Windows10 Enterprise machine on which I want to disable UAC completely in order to execute all applications as Administrator per default.
However, my UAC settings keep resetting every time after a reboot.

I tried the following solutions:

  • Setting the following values in the registry hive HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System:
    • EnableLUA to 0
    • ConsentPromptBehaviorAdmin to 0
  • I even made myself the effective owner of the registry hive above and denied every other user (incl. SYSTEM) to modify it.
  • Setting the following group policies:
    • Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Behavior of the elevation prompt for adminsitrators in Admin Approval Mode to Elevate without promting
    • Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Run all administrators in Admin Approval Mode to Disabled
    • There is an other setting somewhere around Computer Configuration\Administrative Templates\System\ ??? which disables the automatic overriding of Group Policy Settings.
  • Reinstalling a fresh copy of Windows10
  • Writing a script in C# executed on every boot which sets all these settings for me - it did not work as not even Admin Privileges apparently are high enough to change these settings...

None of the above solutions --including the Windows re-installation-- helped resolving the problem.

I am aware that Windows10 has trouble running the WindowsStore and MSEdge etc. when one has UAC completely disabled - but I do not care as I do not use any of these "features".

Does anyone have a solution which I have maybe not yet tried?

As a developer, this drives me completely nuts.

Completely disable UAC in Windows 10 is not a duplicate of my question, as I have tested all the proposed solutions in the linked question and they did not work for me (as specified above).

  • @Run5k: Not really, IMO, as the proposed solutions did not work for me (as I already stated in my question). – Unknown6656 Jul 7 '18 at 18:03
  • @Biswapriyo: I had the value PromptOnSecureDesktop already set to 0 on my machine (You couldn't know that, I did not mention it). However, the 3rd line does not make sense to me, as I need to disable UAC prompt, and not enable it. Setting EnableLUA to 1 does enable UAC-prompting according to MS Specifications and to my experience. – Unknown6656 Jul 7 '18 at 18:16

    If you use Process Monitor (could be boot, can also do shutdown), to monitor the EnableLUA key that is reset - I assume this is at least one that is reverted, it might reveal from the stack of the reg key write operation, the process, module and function from the stack, could provide more insight at least. – HelpingHand Jul 7 '18 at 19:25

    @Run5k: The earlier question is from 3 years ago. Windows 10 has had multiple updates since then and Microsoft keep dicking around and removing features that used to work. The fact that it worked for the original user is irrelevant because Windows 10 itself has changed a lot since then. – Rex Jul 23 '18 at 14:34

Open gpedit.msc and navigate to Computer configuration -> Windows settings -> Security settings -> Local policies -> Security options. Under that, disable User Account Control:Run all administrators in Admin Approval Mode.

Here's what the documentation for Admin approval mode says:

If a computer is upgraded from a previous version of the Windows operating system, and the administrator account is the only account on the computer, the built-in administrator account remains enabled, and this setting is also enabled.

This is indeed the case for me - I have upgraded from Windows 7 Ultimate -> 8.1 -> 10, and mine is the sole administrator account. If that's the case for you too, well - seems this can't be fixed without a fresh install of Windows with a separate administrator account.


If your domain Group Policy is overriding your settings, the method described here might work.

To make your life easier, I made a task you can import into Task Scheduler:

<?xml version="1.0"?>
<Task version="1.2" xmlns="http://schemas.microsoft.com/windows/2004/02/mit/task">
      <Subscription>&lt;QueryList&gt;&lt;Query Id="0" Path="Microsoft-Windows-GroupPolicy/Operational"&gt;&lt;Select Path="Microsoft-Windows-GroupPolicy/Operational"&gt;*[System[Provider[@Name='Microsoft-Windows-GroupPolicy'] and EventID=8004]]&lt;/Select&gt;&lt;/Query&gt;&lt;/QueryList&gt;</Subscription>
    <Principal id="Author">
  <Actions Context="Author">
      <Arguments>ADD "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System" /v EnableLUA /t REG_DWORD /d 0 /f</Arguments>
      <Arguments>ADD "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System" /v ConsentPromptBehaviorAdmin /t REG_DWORD /d 0 /f</Arguments>

The bug seems to have gone away in the Windows10 build 1803 / 17134.523.

I will close this question although this is technically not a valid answer to my question.
