Working on my parents’ computer this evening, and it appears WinZip overrode the built-in zip/unzip functions of Windows. Context menus were only giving me the option of opening my zips with WinZip, but the trial had expired so I couldn’t actually unzip anything.
A manual uninstall of WinZip and a clean install of 7-Zip later, and then I see that the system’s zip functions are suddenly available. It didn’t click until then that they were missing previously.
That’s just evil.
I wasn’t used to that behaviour, since I’ve mostly used WinRAR and 7-Zip for the past decade, and neither of them have overridden the system’s zip handling in my experience.
It looks like the nostalgic shine that WinZip used to enjoy in my memory just got a little marred.
