I did tech support at different times for both retail customers and coworkers. For people's personal computers I'd make every effort to fix it as it was, and was usually pretty successful. Occasionally there'd be a virus too deep or the thing would be loaded up with so much bloat from the factory that a reinstall was easier, but I'd try to put files back in place and reinstall as many programs as I could. When I was working company IT I'd just wipe and reimage. All their stuff was in OneDrive or Sharepoint, and 90% of the apps were in SCCM. That way I didn't have to worry about missing a problem or weird issues relating to updating instead of installing from scratch, and it was faster so they'd get back to work sooner anyway
