Windows 10: UAC prompt for Task Manager. MMC blocked. What happened?

I don't know if a recent Windows 10 update changed something, or if I have a virus, or what, but my Win 10 Pro 64bit computer is behaving differently today than a day or so ago.

If I try to open the Task Manager I get a UAC prompt.

If I try to open Computer Management, I get a "This app has been blocked for your protection" message for MMC.EXE.

I just downloaded MalwareBytes software and Edge blocked the download because it may be harmful. I was able to select KEEP and install the software. I am currently scanning my system, but nothing found so far.

This messages normally do not appear on my system.

I have not installed any new software recently, except for Windows updates. My user is an administrator and the only user on the system.

One other item I've noticed is that some apps can take many minutes before they open. An example is Notepad. I clicked the icon in the Start menu and nothing happened. I then clicked on Notepad++ and it opened right away. After a few minute Notepad showed up.

This is a 64 bit Windows Pro installation, build 19042.685 of version 20H2 with experience pack 120.2212.551.0.

Can someone tell me why this is happening and how I could fix it?

FYI... MalwareBytes scan just finished and found no issues. I am installing TrendMicro Housecall now to perform another scan.

Task Manager prompt for elevated ID / password on Windows 10

In Windows 10, the task manager starts elevated every time and get hits with UAC every time when we check CPU and processor usage or view list of running proceses to see if Outlook closed completedly.

The task manager ran non-elevated, and you didn't face a UAC prompt in ​In Windows 7, verified all GPO settings is same as Windows 7 applied for Windows 10.

Any way to supress this Task manager UAC.

Thanks & Regards,

Grant a specific application permanent UAC permission

Hello jaksps,

In line with your concern, User Account Control doesn't have a "allowed-or-blocked" list and disabling the User Account Control involves security risks. Though, there is a workaround to run a program without UAC prompt using Task Scheduler. I'd recommend
performing the steps suggested by SpiritX MS MVP in this
thread.

Looking forward to your response.

Regards.

 

Meaning of the various colors used in UAC prompts.

We suggest you to check on this link for more information
with UAC controls.

The following are examples of prompt coding:

• The application blocked by Group Policy or blocked from a publisher.
  
  
  
  

• An Administrative application like Control Panel that is asking to allow to run on your computer.
