02What it does

Every MSI and most installers register an entry under ...\Uninstall, so this key is more complete than Get-Package and scriptable for inventory — including per-user installs under HKCU:\...\Uninstall. On 64-bit Windows, 32-bit programs land under the Wow6432Node subpath, so query both or you will miss roughly half the software. TheQuietUninstallString and UninstallString values also give you silent-uninstall commands for scripting removals.
