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

If using the mouse at idle causes 30% cpu use, I could see that causing some problems when running a cpu intensive application.

True, but the OP didnt say that .. he cited no performance related issues period.. and if you're using your mouse, your cpu is not at idle

Well, actually I still don't see any speed performance decrease, really.

And as I've said earlier, it jumps to 30% EVEN WITHOUT moving the mouse, and I'm sure you guys consider that IDLE.

So with that said, that's really a problem. 30% explorer.exe load even without doing anything?

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.

A chipset or mouse or wi-fi driver update is in order for the OP. The sustained CPU activity in explorer.exe likely indicates chipset.

My chipset and every driver you can think of with my laptop are all updated, including the chipset, intel matrix storage manager, and etc.

I disconnected all of my USB devices and used the touchpad instead, still the same problem.

And also, even without moving the mouse the problem still persists. So there CAN be a possibility that this is not a mouse issue at all.

Just because said drivers are "up to date" doesn't mean they work properly.
