While working on my Windows 7 installation image, I need to remove the VMware Tools prior to sysprepping.
The setup64.exe that VMware provide does have a silent option, but that still comes up with a confirmation window.
The proper way to do this is by running:
MsiExec.exe /quiet /norestart /X{2323AB98-DC8C-4883-9560-877CA97E1F61}
This goes for the version I have (8.8.4.14177).
To find the correct UID for the software, take a look in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall - it should be in there.
Find the UninstallString, and add the /quiet and /norestart options.
