Coach used to tell me an Expert was a has-been drip under pressure lol. IDK, the basic stuff is posted all over this thread...backups. malware hunts. verify specifications. The user's Data should never be lost, their system should be readily restorable to a last-known-good condition.
Beyond that, its try this-try that, look stuff up, ask for help; sometimes, pray a new os or update will take the issue out on its own..
But somebody dedicated to the proposition, well they might just debug the installer from another system, figure out what exactly isn't working, and fix it. So far I have not had to do that, and I've run every microsoft operating system that ever existed.
