Search for Details on Installed Software with Powershell

Anyone that has ever queried for installed software knows that win32_Product is annoyingly slow.  There are plenty of solutions out there to pull in all installed software, then filter, then act but I wanted something lightweight and could drill down to my target in a single function.  The script below doesn’t validate that targetAttribute name is legit in the registry but can be used to query for any attribute matches you may be targeting.

.Synopsis
   Function to search Windows registry for information about installed software using multiple attributes
.DESCRIPTION
   Software installed on Windows clients will generally store product information (version, name, uninstlal string) in the registry.
   This function can be used to search against multiple attributes and compare against known values.
   The default mode matches targetData exactly.  The fuzzy switch enables a like operator to be used with wildcard searches.
.EXAMPLE
   . C:\Find-SoftwareRegistryInfo.ps1 -targetAttributeName 'DisplayName' -targetData 'Sketchup*' -fuzzy
.EXAMPLE
   . C:\Find-SoftwareRegistryInfo.ps1 -targetAttributeName 'Publisher' -targetData 'Microsoft Corporation'
.EXAMPLE
   . C:\Find-SoftwareRegistryInfo.ps1 -targetAttributeName 'DisplayName' -targetData '*Office Professional Plus*' -fuzzy
.EXAMPLE
   . C:\Find-SoftwareRegistryInfo.ps1 -targetAttributeName 'DisplayName' -targetData '*Office Professional Plus*' -fuzzy | ? {$_.uninstallstring -notmatch '^msi'}
