Clear Windows Installer queue

article #1315, updated 33 days ago

Sometimes Windows Installer will pile up a queue of items to be installed. These will show up as multiple ‘msiexec’ processes in TASKMGR. To clear them:

msiexec /unregister
taskkill /f /im msiexec.exe
msiexec /regserver

The idea is, first we take Windows Installer offline, then we kill any leftover stalled / queued processes, and lastly, we bring Windows Installer online again. Unless there’s something else in the backgrounds starting more of these things, this will take good care.
