⚠All designs like UI's, features and others in this concept belong to me (AR 4789) This is NOT an actual/real OS or software, this is just a concept, so there is no ISO for this OS.⚠

Music:
Jo Cohen & Sex Whales We Are
Jeremy Blake Exhale*
Windows 11 Remix

* Since 2023, the music of Tobu in NCS (including Infections, which was put on this Windows 12.1) is no longer FreeCopyright. So I decide to replace the music to avoid the Copyright Claim.
