What’s the Best Way to Cleanly Uninstall a Program Using PowerShell?

If you need a dynamic solution, I recommend just running Start-Process with an arguments list without trying to parse the UninstallString too much. You can grab the relevant uninstall strings directly from the registry and execute them. For instance, gather all the UninstallStrings and use a simple loop to call msiexec with the GUIDs. This keeps your code cleaner and avoids the mess of manual string manipulation.

Honestly, the uninstall string can be a pain! I usually either extract the GUID from the string or retrieve it based on the application's display name. For example, you could get the UninstallString, split it to grab just the GUID, and call msiexec. It can take a bit of trial and error, but it avoids unnecessary complications.

There are definitely different ways to uninstall a program! One method is to store the GUIDs of your apps in an array and loop through them. Here's a quick example: you can set your registry key and then iterate through each GUID, checking if it exists before uninstalling it. This way, you're less likely to miss anything. Just remember, this code isn't plug-and-play—it needs to be tweaked to fit your situation.
