How to downgrade/remove ZODB (or any other module)?

Hi - I have just installed ZODB for the first time. However after I'd
finished I realised that I'd installed a development release and not a
stable release so I'd like to downgrade or remove the current
installation and start again.

I installed via a Windows installer from which I could extract a list
of files and then manually remove (there are 290 files) but is there
some less labourious way of  removing a module ?

Thanks
