About VirtualJohn OS

VirtualJohn OS

Flagship build: Win95-inspired desktop for automation training, integration, demos, guest book, video bay, tools, and archive time travel.

Version nickname: Win95 OS Flagship.

Built so the site feels like an operating system for industrial learning instead of a normal landing page.
