Win 10: the terrible CompatTelRunner is back!

<< < (3/3)

Windows 7 machine:
I accidentally applied all windows updates around the end of May. Since then having troubles sometime after startup -- a total sieze-up of the system -- unable to do anything for a while -- maybe ten minutes, maybe twenty :-/
When the system recovers, anything you attempted to do in the 'freeze-time' gets done, and fast: at this stage today, the taskmanager (Process Explorer actually) got opened and I saw a flash of compattelrunner highlighted in red before it disappeared.

Did the following:
To disable Windows Compatibility Telemetry, kindly follow these steps:

    On the search box, type services and press Enter to open the Services desktop app.

also uninstalled KB2952664 "Compatibility update for keeping Windows up-to-date in Windows 7" as suggested in Superuser:

System is fine on reboot: will report if there's any other problems.

This all happened in the wake of replacing a harddrive which was also causing the system to sieze up (I'm even wondering now was the HDD really on the way out: but I think so). All of which made me suspect the new HDD rather than look for other possibilities...

Less complex than removing it and as a possible alternative workaround, you could do worse than consider using ProcessTamer to Force Kill it.
It's path is usually: C:\Windows\System32\CompatTelRunner.exe
