|I am running Windows 7 and there is no such listing in Task Manager on my computer. |
I also booted into WinXP to see if things were different there. They aren't. Also tried logging into 7 as the administrator, even though I have full administrative privileges in my normal account. Still no hardware interrupts.
My process screen has multiple columns labeled "image name, User Name, CPU, Memory, handles, threads, Image path name".
In Win XP there are less columns labeled "Image name, User name, CPU, memory usage."
There are values in all those columns for each process.
These columns can be accessed by clicking on View at the top of the process screen. Try checking the image path name to see what is actually using the resources.
Is the computer in question a company computer? If so, I suggest you speak with the IT folks about this issue.
I can't recall ever seeing that listing in Task Manager and I have been using Windows for many years.
Perhaps someone else here that may be following this thread will have some additional knowledge.
