My first computer didn't run a Microsoft OS (but it did have a customized dialect of Microsoft Basic in ROM).

My first Windows PC was a Toshiba T4600C, designed for Windows 3.1, but upgraded with an 8 MB RAM card, an 800 MB HDD, and Windows 95 from a 13-floppy set.

Happy 30th anniversary to the version of Windows that gave the world the Start Button and adopted a Rolling Stones hit as its theme song.
