I'm looking for someone to give my desktop a thorough cleanup. The PC runs slower than normal and I suspect cluttered files, temporary data, and unused programs are to blame. I want a calm, step-by-step session where you back up important data, uninstall unnecessary software, clean temporary files, optimize startup programs, and apply basic system maintenance. If possible, please also update or install essential security software and provide simple tips to keep the computer running smoothly. I’m hoping for a 2 to 3 hour session, starting in the late morning.
