- 2 How to Fix Microsoft Compatibility Telemetry High Disk Usage in Windows 10?
Introduction
The number of users using Windows 10 is increasing with every day, and just like every other operating system, Windows 10 also runs on a number of background processes. We may think all these processes are very important for our computer, but they all aren’t. There are many unnecessary processes running in the background. These processes actually have a job, but we are calling them useless because along with doing their job, they are harming our computers too. This is not the first time we have come across such process which is harming our system. It has been in our computers since Windows 7, which is one of the most successful operating system manufactured by Microsoft. It is still used by many. When it was first introduced, it didn’t take long for the geeks to find the reason behind sudden slowness of their computer.
Microsoft Compatibility Telemetry or CompatTelRunner.exe has always been in our Microsoft manufactured operating systems since Windows 2000. But it was first discovered to be causing high CPU usage in Windows 7. It was working fine in Windows 8, but then again, in Windows 10, it is behaving badly. To know more about Microsoft Compatibility Telemetry, you can refer to our other post. We have explained its use and how it is affecting our systems in that post. To solve the Windows 10 high disk usage caused by CompatTelRunner.exe, check out the different solutions below.

I have a fast computer (quad-core i7, 3.5 Ghz, 24 GB of RAM, Windows 8.1) and I installed a new hard drive less than a year ago that was supposed to be as fast as you could buy for an HHD and not an SSD.
On boot, the computer is extremely slow for about 20 minutes (literally 20 minutes). Nothing will load. Opening programs will just hang.
Went into Resource Monitor and found that my disk I/O is at 100% that entire period. In fact, it looks like one program is just going to town on my disk:
CompatTelRunner.exe
. I've Googled it, but there are hardly any results, so I don't know what service this is.Here are some screen shots at 5 and 10 minutes in:
It could be a hard drive issue (Windows 8.1 Update 1 Disk Usage 100%), but HD Tune shows burst rate at 22.8 MB/s and average around 81.0 MB/s

Short answer: it's 'legitimate' disk usage by a MS tool, just like the MsMpEng (MS Malware Protection Engine) it's scanning your disk regularly.
How do I get to that statement?Well, I have had the same behaviour on my Win 7 machines and did some digging. First, I used the Resource Monitor and found CompatTelRunner.exe reading what looked like all of my disks/files, like e.g. a malware scanner does. During that time it was also writing to a directory ( C:windowstempcompattelemetrylogs ). When it was done with the disk work, it started showing network activity on the upstream (matching what is mentioned in an Avast Forum Entry). I checked the above directory and found confirmed what the file and directory names hint at: it seems to be 'Compatibility Telemetry Information'. That means that MS seems to be scanning all PCs that have the update installed (i.e. all that are Win10-compatible), collecting information about all installed programs and features (read: about 'everything'), and then sends at least part of that information or a status report to MS servers (I have not network-screened it.. yet).
The frequent re-releases of the update can mean many different things, like compatibility updates, scan rule updates, anything, really. However, I don't like that MS scrapes all of my machines (and everyone else's, too) for information and does not tell me about it. Even if that information may be helpful or even necessary in providing the seamless upgrade path to Win10.
If you don't want to go to Win10 on that machine, you should consider removing the upgrade.

I had this issue also (I'm on Windows 7, but the issue is identical). Many sources have found that KB2976978 has been re-released numerous times; it's likely that the version of the patch you have is an older release with glitchy behavior. Uninstall it from
Bigbio2002Bigbio2002appwiz.cpl
and reboot. Windows Update will re-offer it next time it checks for updates. I went ahead and reinstalled it and everything seems fine now.3,70411 gold badge1919 silver badges2828 bronze badges

The data facilitates the development team in enhancing the overall user experience and improving the Windows’ performance by fixing probable issues (bugs).
Why Microsoft Compatibility Telemetry is included in Windows 10?
The MS Telemetry tool has been deployed in Windows 10 to facilitate:
- Improving the overall system security.
- Upgrading Windows OS as per what the user wants.
- Augmenting system performance and apart from which make it safer from virus attacks.
Type of Data Collected by Microsoft Compatibility Telemetry
Microsoft Compatibility Telemetry collates data and sends the data to the Microsoft Windows development team, which is inclusive of:
- The typed text from your keyboard, which is sent in every 30 minutes.
- The MS script sends a list of all the multimedia files from your PC.
- The tool would send everything a user says to Cortana (the Microsoft Windows Live Assistant). Apart from which, the full transcription with Cortana is also sent to the developer team.
- The tool transmits the first 35 MB of data from your Webcam on the first usage.
- The type of hardware and also the device driver details are collected and transmitted.
MS telemetry tool collates the data and stores it on your PC and this data is transmitted to the Windows development team. As storage is involved, this works as a trigger to the Microsoft Compatibility Telemetry in Windows 10 high disk usage issue.
