CPU Usage after suspend

#1
I'm using TCMD11x64 on a 64-bit Windows 7 Home Premium.

I usually have a TCMD open with three or four TCC tabs, all of them at the prompt. CPU usage is normal.

After coming back from suspend, continuous CPU usage for svchost.exe is about 25%. It only stops when I exit TCMD.

This cannot possibly have anything to do with TCMD, which is not a service
and cannot affect a separate svchost.exe process.

I'd recommend reporting this to Microsoft as a Windows 7 bug.

Which svchost.exe is showing CPU usage of about 25%?

TASKLIST /L shows the startup command line for each process, including all of the SVCHOST processes.

TASKLIST svchost /L will list all svchost processes that are running.

You can also use the @PIDCOMMAND to determine the startup command line for a specific process ID.

While I am running TCC 11 on Windows XP, I had a similar problem which, upon investigation, turned out to be a printer driver causing all the CPU usage.

Not supported in the x64 Windows API. I don't have a workaround at this
time.

Hmm. Sorry I didn't answer any message in this thread. I get it through e-mail and sometimes it is easy to overlook that a post is an answer to your own question :-)

Anyway, I think it stopped happening a while ago. If it ever happens again, I'll try to get more info about the svchost.exe process.
