Your favorite OS-tan

[Bella She/her]

For the OG girls: NT-tan or 95-tan

Otherwise, SAGE-tan, Whirlwind-tan, OS/2-tan, Amiga-tan, Unix-tan or Snow Leopard-tan

(Not counting any of my characters ^^; )

Even if I've used a wide variety of Windows, from 3.1. to 10. XP still ended up being one I have most fondest memories of just working so well.
First PC I bought with my own money was a laptop with XP Home, but even then I think Saseko has a nicer design.
Though, Moseko is hugely underappreciated.

[Bella She/her]

Same boat. My computer used XP Home so I was obligated to love Homeko, but Saseko was my preferred design aesthetically.

Moseko might have been (be) my favorite of the XP group tho, I loved seeing a more voluptuous character in a lineup of (mostly) skinny queens.

Second and third to Obabasama I like Nanami and Homeko
