How to make a simple quiet uninstaller with NSIS?

A very long time ago I seem to remember using an early version of NSIS to monitor an install then creating an install & uninstall scripts that could be executed quietly (/silent) by it doing a registry compare before and after. Unfortunately I can't seem to figure out how to do this with the latest NSIS. I'm actually only interested in the silent uninstall script creation at this time so that a program which doesn't have a silent uninstall option and lots of pop-ups can be uninstalled instead from a command line script. Any advice on this please?

I really have no clue what you are talking about.

You can execute NSIS uninstallers silently by using the /S switch. You can make them always be silent by adding "SilentUnInstall silent" to your .nsi

Thank you ... and I remember now, "NH NIS Edit" (& similar) creates the script automatically.
