Created Unassigned: Win32_Products to be avoided ! [22135]

the Get-SharePointInstall function takes a long time to process because it is using the wim (or cim) win32_products class. According to mister google this class should be avoided.
Explanation here:

_When you query this class, the way the provider works is that it actually performs a Windows Installer “reconfiguration” on every MSI package on the system as its performing the query_

and here:

_even though you called a basic query of the Win32_Product class, you actually performed a consistency check of each installation._

in my case I replaced this line
if (Get-CimInstance -ClassName Win32_Product -Filter "Name like 'Microsoft SharePoint Server%'")

with this:

if(Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* ) #| where-Object {$_.DisplayName -like "Microsoft SharePoint Server*"}
