After the GPO installer checks whether the installation was successful

Recently, several programs have been installed with GPOs, how to determine whether the installation is successful?

There's a simple script, like I'm judging if TightVNC is installed on all Win7 systems.

$a =get-adcomputer -filter{operatingsystem -like  "*7*"} -properties operatingsystem  | select name, operatingsystemforeach ($b  in  $a) {if (test-connection - computername  $b. Name -count 1 -quiet) {$b. nameinvoke-command -computername $ b.name {if  ([system.intptr]::size -eq 4)  {  "32-bit" get-itemproperty hklm:\ software\microsoft\windows\currentversion\uninstall\* | where-object{$_.displayname -eq  " TightVNC "} | select-object displayname, displayversion, publisher, installdate    } else {  "64-bit"  get-itemproperty hklm:\software\microsoft\windows \currentversion\uninstall\*,hklm:\software\wow6432node\microsoft\windows\currentversion\uninstall\* |   Where-Object{$_.displayname -eq  "TightVNC"} | select-object displayname,  displayversion, publisher, installdate }}}} 

Note the point:

Do not use WMI when querying installed programs; If I use Get-wmiobject-class win32_product, I can get the same information, but at a speed dozens of times times slower than the registry query;

When querying the registry, differentiate between 32-bit and 64-bit systems, because we can install 32-bit programs on 64-bit systems
