Hi, whenever I startup, I notice that Microsoft Compatibility Telemetry uses about 50-80% of my CPU which stops after a minute or so. Is this normal or should I be concerned?

Hi Tqkend

I'm Juliet and I'll do my best to help you.

The Windows Compatibility Telemetry contains technical information about how the device and its associated software work. It sends data to Microsoft on a regular basis in order to improve the system and improve the user experience. To resolve your issue about its high CPU usage, you can disable this service in the Task Scheduler by following the steps below:

  1. Click Start, type Task Scheduler, and then press Enter.
  2. On the TaskScheduler window, go to this path: Task Scheduler Library\Microsoft\Windows\Application Experience.
  3. On the Application Experience folder, look for Microsoft Compatibility Appraiser.
  4. Right-click on it, select Disable, and then confirm to complete the process.

I hope it helps! Let me know the results.

Have a nice day ahead and Stay safe always :)

Hey I found a fix, I just went to that file location of that "Telemetry"

In my case it was at : C:\Windows\SysWOW64

  1. Renamed "CompatTelRunner.exe" -> "Something.exe"
  2. Then Ended the task on taskmanager then it didn't start up.

Of course I am not sure if it will have any long term effects. Do it at your risk :)

    I found this exe file under C:/Windows/System32 and I can't rename it or change its permissions without the approval of group Trusted Installers. Oh, and the Task Scheduler does not contain it either.

    You have to take control of the file first (ownership).

    Right click and select 'Properties' then the 'security' tab and click 'Advanced'

    At the top you will see the owner is 'TrustedInstaller' - click 'change' and make yourself the owner

    Close the dialog, right click the file again and then reopen the 'security' tab once more and click 'Edit'

    Give yourself read/write permission and then you can rename the file.

    Be aware that if you run DISM or SFC Windows will probably 'fix' the 'corrupted' file and you will have to rinse and repeat each time - also some updates might replace it.

    So far, it's the only thing that has actually worked for me.

    So I've been able to give myself ownership of the file, but I can't give myself the permissions to allow myself to have full control including write access to change the file name. Any tips on that or is this just been a sneaky fix that Microsoft has done now

    Be aware, I suspect MS monitors these discussions... Not to fix any defects (I've complained for 12+ years, and they blame the user, their products only get worse, and they remove useful functionality with every new version), but to find ways to PREVENT you from getting around their ****.

    I had an interview with them once, several individual meetings with people. There were two common topics at every stage:

    1. You solved this issue how? ... as he's writing done the details of what was used so it could be prevented in the future
    2. How do you handle lying to a customer?

    (These should give you insight as to what kind of company they are)

    Speaking of illegal and Linux, they released a version of Edge for MAC. And then, behind my back, without permission, with no warning or preparation, they just "auto-updated" it one day. I launch it and it announces "This app is not compatible with the version of your OS...".

    In other words, they crippled the computer that I own. And were happy to do it.

    That unit is now Ubuntu.

    Also, by the way, the newer versions of Outlook (PC and Web) regularly send your data and even credentials to MS, on the grounds they want to sync the material for a "better experience". My employer uses Outlook, so I occasionally use the web version on my personal PC, and I am always getting popups... Something like "The server is requesting to receive your clipboard contents. Yes/No". Thankfully my browser is a build with lots of protections.

    "SUCK" is not strong enough of a word to describe their behavior.
