I'm looking for someone to give my desktop a thorough clean-up. I want a fresh start with a faster system: remove temporary files, uninstall unused programs, organize files, and run a basic health check. Please also advise on decluttering my downloads and desktop, and set up a simple backup plan if possible. I value a careful, non-destructive approach and would prefer someone who can explain the steps as they go. Access to my computer will be remote, or in-person if convenient, and I can provide administrator access if needed.
