Need help cleaning and optimizing my computer system

I’m looking for someone to clean up and optimize my computer. It’s a mid‑tier desktop running Windows, with a mix of personal and work files. I’d like a thorough cleanup: remove unnecessary programs, free up disk space, run malware and virus scans, update system and software, clean temporary files, and organize my folders. I’d also appreciate advice on performance improvements and basic maintenance tips to prevent future slowdowns. Please bring your own USB drive for any tools if needed, and let me know if you require access to my Wi‑Fi or any accounts during the session. I’m hoping for a friendly, careful approach and to schedule for the late morning if possible.
