Uninstalling stubborn Windows apps
Adobe Refresh Manager / Acrobat Update Service
After uninstalling Adobe Acrobat through Settings > Apps, I noticed that the "Acrobat Update Service" was still running, even after a reboot. There are some suggestions (e.g. here) for uninstalling it by manually stopping services and deleting files, but it would of course be nicer to have a clean uninstall from the original installer package.
It turns out that this is possible through the cached MSI package, which is typically found in C:\Program Files (x86)\Common Files\Adobe\ARM\1.0\Cache and kept in the installer under the name "Adobe Refresh Manager". The following command did the trick for me, using a package GUID retrieved from the registry:
msiexec /x {AC76BA86-0804-1033-1959-018244601149}After running it, the service should be gone and the ARM directory empty.
