I’m looking for someone to perform a thorough cleanup of my desktop computer. Tasks include removing junk files, clearing caches, uninstalling unused programs, running a malware scan, updating essential software, and organizing files. I’d also like guidance on basic maintenance to prevent future clutter. OS is Windows 10, with around 1 TB of data scattered across multiple folders. Please mention any additional steps you’d take for privacy and performance, and whether you can create a clean backup before making changes.
