From google, I found out that this is normal behavior for Windows...Microsoft coders make device manager blank if there is a problem with plugplay. WHY??????????

That is not normal behavior.

According to Microsoft, it is normal behavior.
No Items Appear in the Device Manager List When You Open It

Device manager is blank because your MMC subsystem is damaged or there are missing MMC components.

It sounds like your installation is damaged for some reason, and i would suggest verifying the installation media before anything else.

What you say makes sense. Only, I didn't install Windows 7 on the notebook. It is a Gateway (ACER) brand notebook computer that came with Windows 7 pre-installed. If the installation media is screwed, that means that there are thousands (millions?) of notebooks with a screwed-up Windows installation. Possible, I guess.

Did you send a query to Microsoft to get an answer to that question. The result would be interesting for everybody.

No, I didn't. Do you have good contact information for Microsoft? Feel free to send a query for me, or post instructions on how I can do it myself.

How about Microsoft.com > Contact Us.

OK, I'll try it. Right now. Only I won't hold my breath waiting for a response. If the contact information is that easy to find, they must get billions of queries per second...

I should have known it wasn't that easy. There's no free way to do that, without registering and uploading your product key, which I assume would be on the bottom of the notebook somewhere, if I felt like sending it to Microsoft... (I don't) And before someone gets smart, this was a Gateway (ACER) brand notebook that came with Windows 7 pre-installed.

It is not normal for Plug and Play service to be turned off. Device Manger gets the list of hardware from the Plug and Play service.

Oh, well that would explain why device manager was blank. In this case, plugplay wasn't turned off...it was just using 100% of the CPU. So apparently, plugplay couldn't be bothered to send any info. to device manager.

Which leads us back where we started. There was an apparent problem with a device driver, and plugplay disabled device manager so I couldn't check it out. Nice.

if i just disable Kaspersky Internet Security 2010's Self-Defense and the cpu usage drops, and enable it again it runs for weeks without a problem ^^

Open Kaspersky Internet Security-->Settings-->Options-->unclick Self-Defense and apply and they click it again and apply ^^

Just registered with this site because I have the same prob with Device Manager as you have.I'm running the same system as you are and I am also using an Acer Laptop.Find the same result as you going to Microsoft for help.Can't make anything of Acer either.
When I google the prob it seems that many people have the problem.There are two solutions posted there but neither work for me.Neither does SFC.Seems only thing I am left with is reinstall.
Cheers

I have as well an Acer machine and have similar problems with the PlugPlay service.

Is there any news in the mean time?
