I'm looking for someone to give my computer a thorough clean and optimization. It’s a Windows PC that's about 4 years old. Tasks include removing unnecessary files, freeing up disk space, updating software, running a malware scan, organizing the desktop and downloads, and disabling startup programs to improve performance. I’d also like a quick hardware check and guidance on basic maintenance to prevent future slowdowns. Please confirm you have experience with Windows 10/11, can work on-site at my home, and can bring any necessary tools. I prefer a calm, methodical approach and can provide remote access if that’s easier for some steps.
