Windows 7: High explorer.exe cpu usage when typing.

Hi there,

Did you format the entire Hard drive and reinstall it or just the C partition?

Hi Tofiy,

• What program are you typing "into" when testing this?
• Does the same thing happen with a different benchmark?

Basically I'm wondering if the same thing happens in, say, notepad or wordpad that happens when typing into cmd for example. Are all results the same?

It could also be a driver problem. Make a quick check with Process Explorer and see whether you have a lot of Deferred Procedure Calls (DPC). In PE you see it as 2nd or 3d entry. If you are under 1%, you are OK. 2 to 4% and higher would be a problem.

Then you can also run the Latency Checker. If that shows red bars, something is wrong. It might even tell you which driver is the culprit.
