Definitely Not Windows / Windows 11½ is an independent, unofficial parody project created for humor, satire, and commentary. It is not affiliated with, endorsed by, or approved by Microsoft Corporation.\n\nThis fake operating-system experience makes fun of modern software subscriptions, ads, AI features, updates, storage nags, and the emotional journey of changing your default browser. It is not a real Microsoft product, service, login page, update, store, security warning, or subscription offer.\n\nClippy assigns a random anonymous ID to your browser for a persistent visitor number.

No name, email, password, or browser fingerprint is needed. Clearing this site's browser storage makes Clippy treat you like a suspiciously familiar new person.\n\nTrademark note: Microsoft, Windows, Microsoft 365, Edge, Outlook, One Drive, Teams, Xbox, and other referenced product names belong to their respective owners. This site is a joke.

Buttons may pretend to install apps, sell subscriptions, break Windows, or summon AI, but none of those actions are real.
