Windows has shipped with "ZIP folders" and the ability to create and extract ZIP files since the late 90s/early 2000s I believe (not sure exactly what version.) As of the latest versions of Windows 11, Windows ships with libarchive-based archive extraction, which should let you extract many archives natively (including 7-zip and RAR) via the UI as well as the CLI (via BSD TAR, which also ships with Windows these days.)
I think those first appeared in some form in XP. I don't recall 2000 having support for it integrated into explorer.
ZIP Folders was developed by Dave Plummer from Microsoft (who runs the Dave's Garage YouTube channel). It was made in his spare time, then was licensed to Microsoft afterwards.
