Windows 10: Windows 11 Services using high CPU %

Since December 14, 2023, following a Windows 11 Update, "Services" has been using a 21-25% of CPU , which runs the cooling fan ragged, makes a lot of noise and slows the pc down as soon as it starts. When I launch any software, the fan upticks again in speed. before slowing down again. Something is obviously going on behind the scenes - but what, as you cannot shut off system ntkrnl.exe, which seems to be the process going hyper-active. I tried the solutions in an earlier post from Feb 6, 2022, do a clean boot, disable non MS items at startup, and checked memory with mdshed.exe but afte

Service Host Causing High CPU

Hi,

I suggest you use Process Explorer of Sysinternals tool to identify the service causing this High CPU usage:

 

Service Host: Windows Update - High CPU

- suggests turning off any 3rd party AV somewhere in that

TokenBroker services causes high CPU utilization?

We have Windows 10 Pro version 1703, 64bit.

We see CPU stay at 50-60%, and spike up to 99-100% for extended times. We have been able to isolate the high CPU to the Token Broker service by using the Windows Performance Recorder and Analyzer.

We understand this service has something to do with the Windows Store and Authentication and was added in with the Anniversary update. With it turned off, we return to normal CPU utilization, but we are unsure if this service is a requirement.

Microsoft is a bit ambiguous on this service, even the description for the service reads "<Failed to Read Description, Error Code:1500 >"

• Because there isn't a lot of documentation on this we are unsure if we even need this service. Can we simply disable this service permanently?
• Is anyone aware of the Token Broker service causing high CPU like this?
