  1. I also had the problem of SVCHOST.EXE running the CPU up to 100%. It seemed to happen about the same time I picked up a virus. Infostealer and a trojan horse. I removed the viruses but the problem didn’t go away. I Turning off the automatic updates and that didn’t help. I downloaded and installed the three fixes and then rebooted. The problem still has not been solved.

  2. I tried several fixes for svchost.exe maxing out the cpu. The 3 Microsoft patches did the trick.
