Yes, if the installed apps conform to MS guidelines.
If you open the Registry Editor and browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall you should see sub-keys for each of the installed apps.
Each subkey should have an 'UninstallString' entry, the value of which will show you what command is being used.
It could be an MsiExec.exe switch, a switch on the main application executable itself (e.g. HijackThis) or a dedicated uninstaller program (e.g. Windows Media Player 11's 'spuninst.exe').
Hope this information helps...
