App-V 5 virtual processes

note: I have created a video about this blogpost, see


I have used the function “Get-AppvVirtualProcess” to terminate app-v processes through stop-process. This is not a clean solution but it get things done!

I was wondering about a better solution for terminating App-V processes. Playing around with “Get-AppvVirtualProcess” i noticed the results are processnames and not the packagename.

PS C:\WINDOWS\system32> Get-AppvVirtualProcess
Handles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName
——-  ——    —–      —–     ——     —  — ———–

For an overview of options i used Get-Method on the PowerShell Object.

I find “AppvPackageData” interresting. It shows the following results.

PS C:\WINDOWS\system32> (Get-AppvVirtualProcess -name explorer).AppvPackageData

ProcessId                 : 4736
PackageName               : GNU_NotepadPlusPlus_691_W10
ProcessName               : explorer.exe

The “explorer” process contains two different packages. These packages use dynamic virtualisation to inject themself into the “explorer” process. The property “PackageVersionId” and “PackageId” are the same as “VersionID” and “PackageID”.

I have also tried the same process with a process (firefox) inside of a connectiongroup.

PS C:\WINDOWS\system32> (Get-AppvVirtualProcess -name firefox).AppvPackageData

ProcessId                 : 6584
PackageName               : Con_Firefox
ProcessName               : firefox.exe
UserSid                   : S-1-12-1-3104466749-1076728120-162259091-4099479556
VirtualEnvironmentVersion : 2a8bac12-b194-4fe1-987f-259ea8e56ca2
VirtualEnvironmentId      : 340d0276-b01a-4ab4-82d8-3670fb7b7ae3
PackageVersionId          : 2A8BAC12-B194-4FE1-987F-259EA8E56CA2
PackageId                 : 340D0276-B01A-4AB4-82D8-3670FB7B7AE3

The results use the same properties as a single package, although the name of the connnectiongroup is shown. The property “PackageVersionId” and “PackageId” are the same as “VersionID” and “GroupID”.

PS C:\WINDOWS\system32> Get-AppvClientConnectionGroup -GroupId 340D0276-B01A-4AB4-82D8-3670FB7B7AE3

GroupId            : 340d0276-b01a-4ab4-82d8-3670fb7b7ae3

With this information we are able to lookup the packages underneath this App-V process.  The following command shows all the packages underneath the firefox.exe process.

This information is very useable for troubleshooting and automation!
