[Powershell] Uninstall all other versions of a specific application

[CHiLL]

Hello,

I have a PS script that I'd like to run to remove all previous versions of Policy Central except for any that match the current version number. Here's what I have so far:

Foreach-Object {
   Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion, UninstallString | Where-Object DisplayName -Like "*Policy Central*"
   Format-Table –AutoSize}

That code presents me with all items named like 'Policy Central' from the Uninstall key from the registry and also displays the version number, we well as the 'Uninstall String'.

 

How can I utilize that uninstall string for each version of Policy Central that does not match a specific version number?
