I'm looking for a patient tech-savvy person to perform a thorough cleanup of my computer. The goal is to remove unnecessary files, optimize startup programs, run a malware scan, tidy up storage, and improve overall speed. I’m using a Windows PC (recent model) and would prefer guidance on best practices to maintain performance long-term. Some specifics: free up disk space, uninstall unused apps, organize files, update security software, and improve browser performance. I’d also appreciate a quick backup check and advice on future maintenance. Please share an estimated time, what tools you’ll use, and any potential data safety considerations.
