In case you’ve already had at it, for future reference — as CymaticCycle said, the drive wiper is a great tool on CCleaner, but it will only wipe empty space, not empty folders and lefover bits. (CCleaner also cleans best of freeware and comes with the most ‘gentle’ of registry tools.)
Best uninstall program (that’s free) is IOBit’s ‘Uninstaller’, as it has a setting ‘Advanced’ that uninstalls your programme using each programme’s uninstall if it comes with one, if not it uses its own, just like Windows; however, after that it takes you to ‘Powerful Scan’, which will clear out all reg. entries and most leftover rubbish from said programme. For the few that still have a leftover empty file in Programme Files or elsewhere, you can go in manually and delete.
To be double sure, set folder tools in Explorer ‘Tools>View’ on “show hidden files’, then do a search by inserting, in the case of Podium, the name Zynewave, then re-search under the name Podium. (I always search company name, product name.) Then delete or shred anything that turns up, reset to ‘hide folders’ and you’re clean.
Podium is not an offender — a rather minimal install, but many — even respectable — programmes crap all over a registry by writing all sorts of sometimes seemingly unrelated-sounding rubbish. You can run into it years later sometimes. On all programmes, always check Roaming or Local and/or ProgrammeData, unless you already know exactly which normally hidden folders they populate.
I’ve always hated this dodgy ‘game’ Windows allows and programmers play with users — fast and loose with dumping rubbish all around.
