I use CCleaner Free at home. As of this morning (June 4, 2024) CCleaner pops up an advertisement to purchase the Pro version. After clicking the "X" on the first window and "No Thanks" on the second window, CCleaner does not do a clean. CCleaner will perform an "Analyze" but not a "Run Cleaner". I even re-installed CCleaner Free and it has the same result. This issue happens over and over. I am running Windows 10 Pro.
