Windows 10: I am an administrator but I have access denied in services on Windows 10

I always moved Windows services, mainly to stop Windows Update, because whenever executing leaves my connection bad, I have only 4MB of connection. But suddenly I can no longer control Windows services, and I get access denied, but I use an administrator account. I've tried a lot of things I've seen on the internet, but I just lost access. how to solve?
Sorry for my English.


Below I will leave some images to understand better:


(image when I try to run the command.)






(When I try to stop the service through the task manager.)




(when I enter the properties of the service, all options are null, I can not select.)

Could not open Service Manager: Access is denied

Hi,

I downloaded gpu-z - I can run it as administrator, it works great.

Thing is, I need it to be running from a user account to monitor what happens in a given user situation.

But even if I Run as Administrator I get this error message:
Could not open Service Manager: Access is denied

do you know why and a way around this?

thanks,
dani

 

net user administrator /active:no keeps saying access denied.

Hi Rebekah,

It's possible that you're not using an elevated command prompt, causing the Access Denied error. We suggest following these steps to properly disable the built-in administrator account:

• Right-click the Start button.
• Choose Command Prompt (Admin).
• Copy and paste net user Administrator /active:no and press
  Enter. If the command isn't successful, please post a screenshot so that we can study it further.

Let us know if you're able to hide the administrator account after following these steps.

 

Audio Service not starting - access denied


My audio service is refusing to start regardless of what I try on Windows 10 1803.

I have attempted the following:

• Re-installing audio drivers
• Updating audio drivers
• A full virus scan
• A disk check
• An SFC check
• Making sure all the dependencies of the Windows Audio Service are running

None of these have succeeded in changing anything.
Whenever I try to start the audio service, I get this error message:




This made me think it is potentially the firewall messing everything up, so I start up Windows Defender and get this error message:




Are these two problems related, and does anyone know how I can fix it?

EDIT:
The Windows Defender Antivirus Service and Windows Defender Antivirus Network Inspection Service are both not running, and when I try to start them I get this error:




I imagine that this is connected in some way but I have no clue how to fix it.
