Rundll.exe using whole CPU to run appraiser.dll after Feb 2015 updates

Ok so I found this Microsoft Compatibility Appraiser in Task Scheduler and its description is "Collects program telemetry information if opted-in to the Microsoft Customer Experience Improvement Program"

So clearly I need to Opt Out.

I have stopped the task running. Ahh the fans have slowed down now. I have disabled the Task. I have also disabled the AitAgent and ProgramDataUpdater.

Now to investigate how to opt out of your "Customer Experience Improvement Program", because I am not getting an improvement in my experience.

Interesting, I would say it is more a pest. I suspect Microsoft has released errant code when updating appraiser.dll in order to collect compatibility data for Windows 10 and that AVG has picked up that it is gobbling lots of resources.

I simply opted out of the Customer Experience Improvement Program in order to improve my experience of Windows 7.

Same thing here with my quad-core:

Hi,

I have the same problem with "rundll32.exe appraiser.dll,DoScheduledTelemetryRun" hogging one thread to 100%.  

I do remember opting in to the customer experience improvement program, and I believe that's when it started happening (intermittently).

I now chose to opt out from:

Control Panel\System and Security\Action Center\Change Action Center settings

but it is still happening...

Suggestions?

Have the same issue as well. Killed the rundll32.exe a few time in the TaskManager, but googled a bit a found a German website showing where you can disable this particular CPU hog.

Here's how:

- go to Computer Management (right-click on MyComputer>Manage)

- in System Tools rollout go to Task Scheduler > Task Scheduler Library

- expand Microsoft, then Windows

- click on Application Experience

- in the list right-click on Microsoft Compatibility Appraiser and Disable

Simply opting out of "Customer Experience Improvement Program" on Control Panel does not do anything to this particular task.

BTW, if you would look at the Actions tab when the Microsoft Compatibility Appraiser is selected, it lists two tasks for the rundll32.exe and "appraiser.dll DoScheduledTelemetryRun" is one of them.

Simply opting out of "Customer Experience Improvement Program" on Control Panel does not do anything to this particular task.

Thanks for the helpful suggestion.

Of course, one of the reasons why Microsoft posts such a preview is probably to gather as much feedback from such a "build instrumentation" as possible. Therefore I wonder if MS should consider giving the user more control over this feature in a future build, to avoid too many people opting out of the program altogether, and disabling the process in the way that you describe (which will typically happen on low-powered machines, thus skewing the resulting performance figures for the rest) - since the Preview is aimed at advanced users, many will have the skills to do so...

Perhaps a Notification Area icon popping up and asking the user permission to perform an updated "telemetry run" at a chosen time would be more appropriate, given how intrusive this process is on the Windows Experience?
