I believe that most if not all people answering are (established or wannabe) MVP's:

that try to gain "points" or "medals" (to become MVP or to remain one or become a highly valued one or whatever other metric) by being active on the platform.
Whether the answer is accurate and resolves the issue/question asked or it doesn't, it seems like totally irrelevant, most answers are canned/pre-fabricated and usually revolve around formatting/reinstalling OS/updating (no matter what the actual question is about).

(To be fair I've found the network and audio troubleshooters do work about 20% of the time.)
