How to stop 'Microsoft common language runtime native compiler' using 100% of my CPU?

The operation 'Microsoft common language runtime native compiler' is using up 100% of my CPU and hampering my computer's performance. Everytime I end the task, after about 10-20 minutes, I hear my fans start to ramp up again and it is back, using all of my CPU. Is there a fix to this problem?, it gets quite annoying ending the task every 10 minutes.

 

Microsoft Common Language Runtime native compiler high cpu usage

Hi Sherry,

I've installed the latest Microsoft updates and performed a clean boot. My computer still has the same issues. In clean boot mode, Microsoft Common Language Runtime native compiler and Windows Host Processes (Rundll32) are still running constantly and using
up lots of CPU. Windows Backup is also still failing with error code 0x80780166.

What steps should I take now?
