Hello all, I repair and maintain computers in my retirement to stay current and to see all the wonderful (ha-ha) problems that people encounter. I love Windows 10 and think it's Microsoft's best effort ever, especially after the debacle of Windows 8. I'm hoping to possibly learn something from this site, and I would like to hear about people's procedures for cleaning junk off a computer and optimising it. Slow running computers is a problem with at least 50% of my clients. I would also like to share my own procedure for cleaning and optimising if there is any interest from members.
