Hi

Welcome to communities.

first you need to check verify that VMware Tools is installed on every virtual machine on the host.

If yes then you need to go through rest of the steps.

Hi,

The svchost.exe is common one.  To find the specific then you have to enable perfmon and check where cpu has been utilizeed.  i suggest to check with esxtop command from ESX host to check the utilization like cpu wait/ ready value also.

Hi,

As mentioned above check the monitoring. Is the VM monitoring tools showing high CPU? if not then you might need to allocated more memory to that VM. Does it require 8 VCPU's?

Hi All

Thanks for your reply, I have 3 hosts in cluster. I migrated this particular VM to another host, but its still the same issue,

I did a cumulative internet explorer update for that VM, I think 16 GB & 8 vcpu is more enough, I feel it has something to do with 0S level or may be VM.   Whenever it goes high , I login to local administrator and log off then it goes normal.

the VM is part of domain.

Nine years down the road I am encountering the same thing. I don't know what caused it yet but just killing the svchost process made the CPU usage drop to 0% and the VM instantly became snappy.

I noticed the task bar lost its styling though, most of it now looks like Windows95. Only yhte trsay areas and the Start button's background is still blue. I then killed Explorer.exe and restarted it using Task Manager and everything looked fine again without the CPU hogging.
