After removing CC (PS&LR). Running Adobe Clean tool, and manually checking all files in "Program Files" are removed.
Reload CC (LR & PS).
Open Task Manager, Open Lightroom | Open a Catalog
In Develop Module.  And do nothing with LR.
Task Manager reports LR is using approximately 750MB of ram
About 10 minutes later This has climbed to 1.1 GB Ram and continues to climb with no activity being done in LR.  It continues to use between 10% to 15% of the CPU.

What is LR doing in the background to consume the Ram?  Is this a normal activity?

Me, I wouldn't worry about this. What you have reported does not seem to me like evidence of a memory leak. It is evidence of background activity. Lightroom does lots of housekeeping, like building cached images, when it is open. This is to allow a better experience when you want those resources (previews) later.

I found a memory leak—LR went from a memory footprint of a few GB to 72+ GB in a matter of hours. That was a bug, which has been fixed.

Based on past threads I resolved this problem.  After looking in my PC I found that I had all the major and minor version updates since LR5.  So I removed LR, PS, and CC desktop (important to remove this one). 
Keep app preferences!
Restart
Now go back and reinstall CC desktop.  Once you log on, it will pull everything else down.
Memory problem solved.

In a zero image catalog, LR consumed between 175MB and 210 MB of RAM.  Even after being left on overnight.  

This was a combination of the background processes running in LR and I had a bunch of unnecessary old software on my PC.
This actually operates faster now.
