Silent (Unattended) Uninstall of Dell Command | Update

TL;DR:

MsiExec.exe /X{EC542D5D-B608-4145-A8F7-749C02BE6D94} /quiet /norestart

I needed to silently uninstall Dell Command | Update, and a Google search for such currently doesn’t turn up anything helpful. Their user’s guide is equally unhelpful, telling me to “see the operating system documentation…for information on uninstalling programs.” Thanks, Dell.

 

 

I searched HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall in the registry for an uninstall string, but with no luck. I then searched the registry for the text “2.3.0,” the current version of Dell Command | Update, in hopes of finding the uninstall information somewhere else, since there is an option to uninstall it through the Programs and Features section of the Control Panel.

 

 

That search eventually turned up the key Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\D5D245CE806B54148A7F47C920EBD649\InstallProperties, where we can see MsiExec.exe /X{EC542D5D-B608-4145-A8F7-749C02BE6D94} as the uninstall string.

Running that from the command line starts the uninstaller, but not in silent mode. Running msiexec /? returns the help for this command, which tells us that adding /quiet will run in silent mode. I threw in a /norestart just for good measure.

 

 

 

Finally, we have the following command line command to do a silent uninstall of Dell Command | Update:

MsiExec.exe /X{EC542D5D-B608-4145-A8F7-749C02BE6D94} /quiet /norestart
