Proposed as answer by Andre. Thursday, November 29, AM. Hi, Could you please capture some screenshot for the issue? Wednesday, November 28, AM. In my Task Manager, I saw 2 dwm. Is this normal???

Is there any possibility that someone have remotely login to my computer??? I keep getting this all the time! Hi, I've checked the release version of Windows 8 Pro with this issues. It's the same thing. I believe this is a flaw with Windows 8.
And it's still there in the background when applications are running, managing those applications and the underlying system. It's a graphical subsystem that was introduced in Windows Vista, and it's responsible for the fancy 3D effects that you get on your desktop now.
It drives the "Aero" user interface , so things like glass transparency, Aero Peek, Aero Shake, and a host of other eye candy features are implemented by this process.
Understanding what both of those processes are and what they do should help to explain the phenomenon you cite in your question:. They consume no cpu as such but only consumes when i try to refresh my desktop. I mean when i right click on desktop. When you refresh your desktop, you're invoking functionality provided by both of those processes. Explorer is responsible for drawing the desktop itself programmatically, it's implemented as an iconic ListView control managed by Explorer , and DWM is responsible for the graphics subsystem that gets the desktop, in all its beautifully composited glory, onto the screen in the first place.
That leaves plenty left over for your foreground applications. It's also difficult to monitor exactly what percentage of the CPU those processes are using without altering the results.
But, from the symptoms that you've described, you can be sure that you don't have a virus or anything else wrong with your computer. That's just Windows running, doing its thing.
If you're recently upgraded your computer to Windows 7 from an earlier version like Windows XP , and have noticed your performance slow down as a result, your graphics card may be struggling under the pound gorilla that is DWM. All of the Aero effects are expensive to run—not a problem for today's overpowered and overpriced video cards that generally sit around doing nothing, but a significant performance hit for older systems that used to run just fine with older versions of the OS.
You might try reverting to the Windows Classic theme, which will disable most of the Aero-themed goodness, but will also put some of the "pep" back into your computer's step. Do that by right-clicking on your desktop, selecting "Personalize", and changing your theme to Windows Classic. Both explorer and dwm are "necessary" files that Windows runs.
Similarly, dwm. So it makes sense that you see action on them when trying to refresh the desktop. I've never actually looked to see how much processing power they use at any given time, so I can't say whether that's excessive or not, but there's really nothing wrong with either one; they probably ought to be running, and unless they're causing undue CPU use, you probably don't need to worry about them.
And if you do need to worry about them, then it might be a consequence of your computer not being powerful enough to run Windows 7. All that said, this isn't really a question for this site.
