We are using more than 1000 Windows 10 (20H2) on a virtual platform, but we are experiencing an increase in CPU usage every Friday from 9:00 AM to 11:00 AM. So far, we have confirmed the following.

I output the top 10 usage rates every 15 seconds with PowerShell. Result “System” was the cause of the high usage rate.

There is no period of time when the usage rate rises, task registration and execution.

It turns out that the usage rate of “System” does not increase for terminals that are being operated by users. The usage rate of "System" for the lock screen terminal was increasing.

  • When unlocked, the CPU usage rate will decrease.

I tried to investigate using Process Explorer. However, I gave up because I can't get information on the lock screen.

If the process is unnecessary, we want to stop it. If it can't be stopped, I'd like to distribute the days and times.

We would like to investigate the cause of the increase in usage rate of “System Process”. I would like to know a good way to identify the cause.

We would love to hear your opinion.
