SUPPORT CENTRE
Put in a KB number, a STOP code, an event ID or just describe what the machine is doing. You get the actual cause and a step-by-step fix — with the commands, what each one is for, how to check it worked, and how to undo it.

Diagnostic console
Describe the fault in your own words. The console pulls out any codes it recognises, narrows the cause with a few questions, and lands on the fix that matches your answers. It never invents a fix — if nothing in the knowledge base matches, it says so.
Browse everything
The whole knowledge base, grouped by subject. The platform filter above applies here too, so narrowing to Linux narrows this list with it. Open a topic to see every fault in it.
What is covered
Where this stops. Everything in the knowledge base was written and checked by hand, and every fix says what it changes, how to confirm it worked and how to reverse it. Anything destructive is flagged before you reach it. A KB number that is not in it gets a live lookup against Microsoft's own site — but that returns references, not a fix. Microsoft retired the numeric KB URL, so an article can no longer be retrieved from its number alone; what comes back is the documentation and the Q&A threads that mention it, labelled as such and never dressed up as a procedure. When something needs a human, get in touch.
