Windows 10: Win11 fails to start devmgmt.msc because it doesnt have an app associated with it? How is...

When i try to run devmgmt.msc through Run Windows+R it pops up an error window:"This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator."But i AM the administrator. Ok, i use Run as administrator Ctrl+Shift+Enter. Windows pops up next error:"This file does not have an app associated with it for performing this action. Please install an app or, if one already installed, create an association in the Default Apps Settings page."Please suggest a solution.Also please advice, does Microsoft intend to make Error popup text copyabl

get/devmgmt/mediahandlingdyn.xml

My LaserJet Pro M203 is randomly printing pages of code. It will print several pages with the following command on several lines: GET?DevMgmt/MediaHandlingDyn.xml HTTP/1.1. Then it will print a page with the following command listed one time: GET/DevMgmt?ProductConfigDyn.xml
HTTP/1.1.

I have powered the computer/printer down and disconnected the power cord. I have uninstalled/reinstalled the printer. I have purchased a second identical printer which has the same issues. This suggests to me that I have a Windows problem and not a printer
problem.

I have cleared my print spoolers and restarted my computer. On occasion that has corrected the issue, but if I need to restart my computer, the same issue resurfaces.

Any suggestions are SOOOO WELCOME!!!!

 

Pinning .msc Items to "Start".

Actually, step 2 is unnecessary (unless you really want to add it to your All app list too) . You can create a shortcut on the desktop, right-click on it and pin it to Start from there. When done you can delete the desktop shortcut without affecting the pinned tile on Start.

 

Pinning .msc Items to "Start".

I just typed gpedit.msc into the search box and when it showed in the results
rightclick/ pin to start

(running classic shell)
