Canon's Digital Photo Professional 4 is running very slowly on my PC. My PC just meets the minimum requirements for RAM - 4 GB. I had a topic on geeks where the "geek" explained how to use CCleaner and analyzed my startup programs. I had been referencing that topic about every year. Now when I click on My Content, it only goes back to 2015. Is there a way to get to my older topics? I thought if there were programs running on startup that I didn't need, I might be able to improve performance.
