How entries work.

Dated

Every entry shows when it was last verified, and gets updated when Microsoft or Apple ships a fix. Stale advice is worse than no advice.

Sourced

No invented claims. Each fix cites the Microsoft incident ID, support thread, or official documentation it came from, with the date.

Fixable by Anthony

Each entry is something Anthony AI performs in a Vision remote support session: you paste a one-time code, watch every step live, and the session caps at 20 minutes.
