WMI unsecured apartment. Na the sink process wey dey receive asynchronous WMI callbacks for client, no be the provider host and no be the performance adapter.

Wetin you need know

unsecapp na the unsecured apartment callback sink, no be the provider host.

unsecapp.exe dey implement IWbemUnsecuredApartment make client fit receive async WMI events inside dedicated process. WmiPrvSE.exe dey load CIM providers. WmiApSrv.exe dey expose WMI data as performance counters. To end the sink no dey stop Winmgmt.

E safe?: Check the running file path, signature, and publisher. Name alone no fit confirm say e safe.
The same thing with WmiPrvSE?: No. Na this one be the callback sink
I suppose end am?: The async consumer go lose events

Feex tok say

If I see unsecapp near management tool, I dey find the WMI consumer wey open the sink. I no dey treat this filename like WmiPrvSE just because both of dem carry WMI.

Wetin be unsecapp.exe?

unsecapp.exe na the unsecured apartment callback sink. WMI client wey want async events dey tell WMI make e host IWbemUnsecuredApartment here. E no be WmiPrvSE.exe, wey dey load provider DLLs, and e no be WmiApSrv.exe, wey be the performance adapter.

Wetin e dey do?

E dey forward IWbemObjectSink callbacks go the client so that WMI fit call back without taking over the client process. E no dey answer CIM queries and e no dey publish performance counters.

Wetin make am dey run?

Inventory tool, script, or vendor suite open asynchronous WMI subscription. Quiet PC fit still show am after one-shot event query. High CPU here na the consumer, no be second provider host.

Inspect the running instance

Inside Windows PowerShell, this read-only query show matching process IDs, creation times and executable paths on this PC. (pcm)

Get-CimInstance -ClassName Win32_Process | Where-Object { $_.Name -eq 'unsecapp.exe' } | Select-Object ProcessId, ParentProcessId, CreationDate, Name, ExecutablePath | Format-List

No result or a path we no fit access is inconclusive. Protected processes fit restrict access, and process IDs fit be reused. Keep personal paths local. (pcm)

Use the file-identity guide to compare signatures and product metadata. A filename alone no fit establish safety. (pcm)

E dey safe?

Check dis running file

The Microsoft sink dey inside System32\wbem. Any unsecapp.exe inside Downloads no be the unsecured apartment. The real file na callback host, no be WmiPrvSE.

Compare the recorded location with the actual file. A familiar folder alone no fit establish identity. (pcm)

C:\Windows\System32\wbem\unsecapp.exe

Expected publisher: Microsoft Corporation
Folder na System32\wbem, near WMI binaries
Sibling jobs: WmiPrvSE (providers), WmiApSrv (perf adapter)

I fit end am?

E dey drop async events

To end unsecapp.exe go shut down that callback sink. The client go stop to receive those WMI events until e open another apartment. E no dey unload CIM providers inside WmiPrvSE.

I fit comot am?

No delete unsecapp.exe. Async WMI clients need this sink. Stop the consumer application if you want fewer callbacks. Leave the System32\wbem file alone.

E suppose start with Windows?

WMI dey start am when client need unsecured apartment. E no be Startup Apps checkbox.

Measure resource use

Measure the current process rather than assume a universal baseline
CPU and memory	Compare several observations for the same PID and workload. This entry get no independently measured universal baseline. (pcm)
Disk and network	Attribute activity to the actual process and current task; a filename alone no fit establish expected destinations or transfer volume. (pcm)

File information

unsecapp.exe file information
Executable name	unsecapp.exe
Recorded installation path	C:\Windows\System32\wbem\unsecapp.exe
Publisher	Microsoft Corporation
Signature check	Inspect the actual file; this entry no dey certify its certificate identity. (pcm)

Common wahala dem

People dey kill am thinking say na WmiPrvSE

Provider Host na different image. This process only dey hold the async sink. The query storm, if e dey, still dey inside the consumer or inside WmiPrvSE.

E hang after monitoring suite uninstall

Leftover subscription fit keep the apartment alive. Remove the suite completely, then reboot, before you touch WMI repair.

How to troubleshoot

Diagnose before you change anything wey fit scatter things.

Identify the WMI consumer first

Process Explorer: parent, command line, and who open the COM sink. That app na the main matter. unsecapp na just the mailbox.

No reset the WMI repository because this filename appear

Live unsecured apartment na normal thing during async queries. Repository reset na for corruption, no be for visible sink.

Check the identity of running file

A filename alone no fit establish safety. Verify the actual path, signature and product identity. (pcm)
