Need help cleaning up my computer and optimizing performance

I’m looking for a friendly technician to clean up my computer and improve its performance. The PC is a Windows 10 machine with about 7 years of use, currently running slowly with frequent startup delays. Tasks needed: remove unnecessary programs, clear temporary files, optimize startup items, run malware scan, update drivers, and improve overall speed. Please explain any changes and provide simple maintenance tips for future. I’d prefer a hands-on service with a diagnostic check and a clear plan before proceeding. Access to remote assistance is a plus if on-site isn’t possible.
