I downloaded and installed one of the monthly Windows 10 Cumulative Updates.  After the installation, I tried to use CCleaner to remove the 2.87 GB download but could not do it.  I was forced to use Micrtosoft's Windows 10 Disk Clean to perform the cleanup.  Is this because I have the free version of CCleaner on my computer?  Does the PRO version perform this function?  The reason I ask is that How-To-Geek had an article in their newsletter today that Microsoft is planning on removing Disk Cleanup from Windows 10 and I wondered what I could use should that occur, to remove the residual Windows 10 Update download files.
