I'm looking for a patient IT helper to perform a thorough cleanup of my laptop. It runs slowly, has too many startup programs, and I’m getting frequent crashes. I’d like a general cleanup: remove unnecessary software, optimize startup, clear cache and temporary files, run a malware scan, update drivers, and organize files. Preference for someone who can explain what they’re doing in simple terms and can schedule during daytime hours. Please confirm you have experience with Windows 10/11 or macOS, and provide an estimate of time and any tools you’ll use. I’m hoping for a clean, responsive machine by the end of the session.
