Windows 7: Explorer.exe taking up 15-30% CPU usage when moving mou

I never really suspected Adobe was causing your CPU usage anomoly - with the possible exception of context menu concerns, as it may have pertained to the sustained spike.

You could try using all Vista drivers for chipset and USB devices, but that approaches nonsense.

I wasn't guessing when I posted:

It is not often that I disagree with my esteemed colleagues.

The CPU spike is caused by activity over the USB, which requires CPU time. Yes, your wireless mouse is USB.

You are observing a driver issue, one that may or may not be corrected in the future with a driver update - whether that driver is for your chipset, wi-fi, mouse, or any other USB device. Most historical reports of this anomoly remain unsolved.

For those people experiencing a "normal" spike, you are also affected by this driver issue. Is it a problem? Apparently not.

Troubleshooting high processor usage is best done with a profiler. Unfortunately, there's still no x64 build of KernRate (which is an uber-utility), but XPerf can do something very similar, albeit with more pain involved.

If you're still keen to troubleshoot, you might want to download the x64 build of the Windows Performance Toolkit (WPT):

Windows Performance Analysis Developer Center

Let us know when you've installed it and I or someone else here can show you how to use it to find the bits of Explorer.exe which are supposedly chewing your processor(s) when you move the mouse.

Thanks for the help I am keen in solving this.

Done installing it

- Get ready with that mouse.
- From an elevated (run as admin) command prompt: xperf on DiagEasy
- Start moving that mouse as fast as you can without accidentally throwing it out the window. Keep it going for at least 30 seconds. Note the start and end times as close as you can to the nearest second.
- On the same elevated command prompt: xperf d CpuGoingNuts.etl
- Start the XPerf utility (start menu) and load up that ETL file you just created.
- Use that foldaway control on the left to select counters which you believe to be relevant... or zip up the ETL file and upload it here - I'd like to take a look. (There's nothing personal in it unless you're running processes whose names you'd rather not reveal.)

That's weird, when I type: xperf –on DiagEasy , I get an error of:

C:\>xperf -on DiagEasy
xperf: error: NT Kernel Logger: Cannot create a file when that file already exis
ts. (0xb7).

Why is that?

Probably because you ran it a second time with the "-on" switch without first stopping and dumping ("-d"). Use xperf -stop and then start it again.

Sorry, my bad, the "DiagEasy" preset doesn't include something I need. Please do that one more time except start the logging this way instead:

xperf -on base

Then dump and save this way after reproing the high processor usage once again:

xperf -d baseProvider.etl
