Runtime Broker kept thrashing my system, usually using 40% of my CPU although memory use wasn't much, according to the Task Manager. I'm currently using Windows 10 Pro x64 version 10240. How to stop "Runtime Broker" from running constantly in the background.

Understanding the Context

Running win 10 Home 32 bit upgraded from Win 7 Home Premium Then I tried to access RunTime Broker following the procedure below. Launch DCOMCNFG from command prompt running as Administrator. Console Root > Component Services > Computers > My Computer > DCOM Config > Runtime Broker > Properties > Security > Launch and Activation Permissions > Edit Hi! I've been getting Runtime Broker error messages recently-they keep appearing on the reliability Monitor.

Key Insights

I've attached 2 screenshots. Yesterday I used a macrium ... I have the f and r folders... and their runtime brokers are 6.25 KB in f, and 6.16 KB in r. And the lone runtime broker is a Microsoft file, 100 KB in size.

Final Thoughts

All three are dated 1/12/2021 at 1.09pm. That looks like a Microsoft Tuesday update. Yep... 1/12/2021 was a Microsoft Tuesday Windows update. It was KB4598481 KB4598481 Servicing Stack Update for Windows 10 v2004 and v20H2 Jan.12 Also ... Hi!

After 1709 update I found these two instances of RuntimeBroker.exe in my tasklist: and I disabled Cortana in previous version (and mantained it disabled)... so: why these two programs are running?
