Change to using Add-WindowsPackage or DISM instead of wusa.exe (install slowness and uninstall problems)

WUSA is slower in some cases than Add-WindowsPackage (or possibly DISM if pre-Windows 2016) - For reference, see https://dennisspan.com/slow-installation-of-msu-files-using-the-wusa-exe/

Also, choco uninstall of an MSU removes the PACKAGE but not the actual hotfix in WinServ2016 (confirmed), and win10 (anecdotal) since wusa.exe /quiet does not function correctly. See https://social.technet.microsoft.com/Forums/Lync/en-US/f6594e00-2400-4276-85a1-fb06485b53e6/issues-with-wusaexe-and-windows-10-enterprise?forum=win10itprogeneral for reference

The latter is a bug. Should this ticket be separated into Enhancement (install) and Bug (uninstall)?

Start by examining how Chocolatey currently uses wusa.exe, then compare Add-WindowsPackage and DISM for MSU installation and removal on Windows Server 2016 and Windows 10. Resolve whether the installation enhancement and uninstall bug should be handled separately, and verify that uninstall removes the actual hotfix rather than only the package.
