Disabling Windows Compatability Telemetry

Hi,

Thank you for posting your query on Microsoft Community.

As per the description, I understand that you are facing some issues with Windows.

I would suggest you to uninstall Windows update KB number 2976978 from the Windows updates and check if that helps.

I would suggest you to hide the update if you does not want to install.

Refer to the link given below.

Hope this information helps. Please let us know if you need any other assistance with Windows in future. We will be happy to assist you.

I am experiencing the same problem since the last set of updates. However, I am confused by the suggestion to uninsall update KB number 2976978 as this seems to be "diagnostics on the Windows systems that participate in the Windows Customer Experience Improvement Program". I am opted out of the Customer Experience Improvement Program so this service should not be running at all?

Can you suggest a resolution? It seems that Windows constant downloading, installing and assessing for updates takes up some much of the system resources that the computer is pretty much unusable.

I did follow this guidance to remove the malware, but I found it on my computer yet again today.

Compattelrunner.exe from Microsoft is malware

This is the third time my computer has exhibited slow performance, and the third time I have found this malware (as defined by unauthorized installation and highly undesirable effects) on my computer. I deleted two previous Microsoft updates that caused this problem, but now it is back again. Microsoft Update, despite my settings, does not ask my permission to install this.

I am accordingly taking the following actions.

(1) I am posting the indicated screen shot, and accompanying story, on social networking sites to make sure as many people as possible know that Microsoft is distributing what is effectively malware to its customers, and reinstalling it after it is deleted. The screen shot is an excellent visual description of the effects of this unwanted software/

(2) I will be writing Windows 7, 8, and 10 the worst possible recommendations on Amazon.com and elsewhere.

(3) I filed a complaint with the FTC regarding Microsoft's effective sabotage of my computer.

The problem is https://support.microsoft.com/en-us/kb/3035583 which was installed without authorization despite my settings that say to ask permission first. I just deleted it, but how do I keep this malware off my computer in the future?
