Trial and Error is the name of the game when it comes to computer software, especially Microsoft OS. A guy can spend hours searching the net for a solution to a problem, trying this solution or that solution, none work, not even Microsoft's own solution ... then, by T&A (Trial & Error) you finally fix it using a method that was totally undocumented. So, this is what makes a guy a "computer whiz" IMO. The ability to think "outside the box" and solve an issue/problem when no other solution offered works.
