Can someone tell me what this service is? It shows up in all three of my machines running Windows 11, although the 4-digit XXXX is different. Under description it says <Failed to Read Description. Error Code: 15100 >. The path to executable is C:\WINDOWS\system32\svchost.exe -k LocalService -p. Attempting to disable says that parameter is incorrect. I'm thinking some update must've installed it. I ran both Windows Defender and Malwarebytes and nothing malicious was found. Do I leave it alone or manually delete it from command prompt? Thanks.

Found this at reddit...

NPSM stands for Now Playing Session Manager. This service is responsible for showing now playing media on the volume flyout on Windows 10 and on the action center on Windows 11.

Your code shows :
If you are not using a device that uses the CDpusersvc service (printer, scanner, or other types of external device), the quickest and most efficient way of fixing the Failed to Read Description (Error Code 15100) issue is to simply disable it using Registry Editor.

I followed the similar registry entry instructions you just gave for the other other service (CDpusersvc) and it is very similar...one service is just NPSMsvc and the other is NPSMsvc_XXXXX. If you try to disable the latter, it just makes itself again with a new letter/number combination next start. If you disable NPSMsvc it still shows in "Services" but is disabled at start up. I'll see if I have any adverse Windows effects. It's still annoying seeing the messed up service though. I ran sfc /scannow on all of my machines and there are no errors. I'm curious if anyone else has this same service and error now showing.

I think I'll leave it for now...I just sorted all of the services by Description and McpManagementService has the same error under description. I'm not noticing any notable errors so maybe a Windows Update will fix it.

I also have both showing exactly the same in my services. I recently upgraded to windows 11. actually on Nov. 26th and they have been there since the upgrade .I do not know if they were there before the upgrade to be fair. They do not seem to be causing any problems on my laptop and I have just let them be.

I seem to remember some years ago the the connected user stuff in windows 10 had the same errors, which if I remember right was finally sorted out by updates. I bet these will also. The non descriptor is really only a nuisance because you cant see what might rely on it or what it actually is doing. I learned a long time ago though if it aint broke leave it alone. :)
