Does anybody know how to stop the Windows Compatability Telemetry (CompatTelRunner.exe) from starting? It causes extremely high disk usage which results in large performance issues.

    "It works just fine on millions of computers" - Are you really sure about this statement?

    "Start with a clean install.." - This is Microsoft's way to solve software troubles. The fact is that the poor users around the world are not computer engineers and think this may be the solution. Only after days and days spent on a simple clean install, they realize the problem is still there. Just wait until they install all the software they had prior the clean install and the hundreds of Windows updates and see. 

    In the Windows' world, the way to solve problems like this is to buy a new machine. These poor users think a computer gets slow because it's 3 years old and then buy a new one. That's fantastic!

    I am sorry, why can't we as users, demand that MS allow us to disable the process? We should be able to get a million or so people using Windows'10 to insist.  Organize and resist?

    I would like Microsoft to pay for the upgrade.  

    Thanks! I was needing a good laugh today! That made my day!

    I did figure it out.  The root cause of the problem is that the disk is thrashing due to paging i.e. swapping and an IO intensive application CompatTelRunner.exe.  My one terabyte disk was 2/3 used up.  I have a lot of software installed on this laptop.  The laptop had only 8 gigabytes of ram.  

    Telemetry starts at 7:00 PM when I am typically playing an online game such as World Of Warships.  The game has a memory commit size of 1.2 gigabytes before beginning a battle; remember I only have 8 gigabytes of memory.    Each battle involves downloading a huge amount of data before it can start.  The memory commit size is 1.9 gigabytes once a battle begins and the commit size is even .  My system starts paging when a battle starts.  This means it needs fast access to the disk.

    Along comes CompatTelRunner.exe, which starts with a small working set that continuously increases while it runs but does thousands and thousands of disk reads and millions and millions of I/O other.  Procexp64 shows the IO other is caused by 2000 page faults per second!  Ah ha, Microsoft is could be opening a memory mapped file and reading from it.  A page fault occurs every time they read outside of the sliding window.   OR it is possible that they are reading through shared memory or even memory in other processes using a driver of some kind.  Whatever it is the combination of the game and CompatTelRunner.exe page faults is a nogo.  My system is unable to allocate enough virtual memory fast enough for me to enter a battle and my team ends up playing a man short because Microsoft is over using the virtual memory system with their malware.

    So I bought more memory and installed it on my laptop so that Microsoft's malware will not ruin my gaming experience.  This fixed the problem.  I would like Microsoft to pay for the upgrade.
