Windows 7: Svchost.exe Crazy High CPU Usage and Crazy High Memory Usage

I looked & do have Update KB3138612 installed as mentioned in the link, however it was installed a couple days after I had the problem in March 2016.

I have settings to notify me about Updates, not to automatically D/L them. However after I did D/L & install them in March the CPU usage dropped down to 1-2%. FWIW "wuauserv" never appeared in Task Manager but I saw it in Resource Monitor & it was using 25% of the CPU. Even though I'm only being notified about the Updates it still caused high CPU usage for some reason.

I don't recall if was April or May but there was high CPU usage again, and Resource Monitor indicated it was "wuauserv". So I manually D/L and installed the updates & the CPU usage dropped to 1-2%. Could the CPU usage increase just because Microsoft is trying to "force" an update even though it won't go through because Windows is blocking it?

High Memory usage in svchost with Windows Update
