Service TrustedInstaller.EXE permanently active taking up to 50% CPU resources

On my machine (Windows 7, 64 Bit) the TrustedInstaller.EXE is permanently active. The amount of used CPU changes permanently. 2 seconds 0 % then up to 50% (I have a dual core) for a second then down to 0.

Rebooting the machine did not help. Also a complete Virus scan was negative.

I have monitored the process with the Process Explorer tool. I can see that the process always access the same Registry key when it gets active. The key is

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\PackageDetect\Microsoft-Windows-IIS-WebServer-AddOn-2-Package~31bf3856ad364e35~amd64~~0.0.0.

I finally figured out a solution. All you have to do is right click on Process Explorer and click run as admin. Then right click on trustedinstaller.exe and click on suspend. Done :)

It's easy all you have to do is run Process explorer as admin and Terminate the process

The only solution that I have found is the following:

boot computer with Linux

open OS HD

change directory to c:\windows

type "rename Servicing Servicing(1)"

there is one draw back to this, you will have to change it back when you need updates.

I have been doing this ever cence I got the BETA edition, and have never run into any problems.

If Microsoft would allow people to update once a month then there would never be a problem, there has never been a real need for your computer to update daily, and there never will be.

Just to help avoid confusion by sprinkling a bit of accuracy, instead of "Start as administrator," I see "Run as administrator."  Plan on the process adding 10 or 15 minutes to the next boot-up.

And for checking the hard drive for SmartDrive errors, I use CrystalDiskInfo v6.2.1.  (A free utility without malware, as of v6.2.1.)

In my experience, all the utilities for displaying SmartDrive conditions provide the same cryptic, almost impossible-to-understand statistics.  I once googl-ed and wikipedia-ed trying to get a good explanation of how to read SmartDrive data, but I gave up.

Some of the SmartDrive data is understandable.  What isn't understandable is apparently not able to be explained coherently by anyone, and the original engineers died, so they're no help because they're not saying anything.  I'm just saying that if you don't understand most of the utility's output, the problem isn't "you."

At least, CrystalDiskInfo will also provide an easy graphic of your disk's health, which will hopefully be a big, green "Good."  And that's all you really have to know.

You can get CrystalDiskInfo from this good download site:

http://www.majorgeeks.com/files/details/crystaldiskinfo.html

The Majorgeeks download site warns about installing CrystalDiskInfo: "This program is advertising-supported and may offer to install third party programs that are not required for the program to run. These may include a toolbar, changing your homepage, default search engine or other third party programs. Please watch the installationcarefully to opt out."

That's really good of Majorgeeks.  Looks like they're doing what they can to help people avoid what has become an almost-universal scam.

CrystalDiskInfo is still on version 6.2.1.  So if you get past the Installation cleanly, then the utility will be clean.  My CrystalDiskInfo has been opened for an hour, and there wasn't a single advertising nag.

You mentioned that your processor is stuck at 100% half the time, but did you tell us what the processor is?  If you need to, open a Windows Explorer window.  Then, in the address bar at the top of the window, select Desktop.  Then, in the main body of the window, right-click on Computer and select "Properties."   Then, please tell us what it says the offending Processor is that's inside the box?

Thanks,
