I guess this is not a new question and apologise in advance if I am repeating it but I failed to unearth anything helpful through Search:
I upgraded my laptop to Windows 10 one month ago. Reliability Monitor, which I run every day, has advised me four times since May 22nd that Microsoft Compatibility Telemetry stopped working. The application name is CompatTelRunner.exe at C:\Windows\System32.
1. What causes it to execute and how often might that be - are the four times so far likely to be its total attempts?
2. Other than suffering its periodic appearance (I am comforted by a straight line 10 in Reliability Monitor), I wonder if there is a simple solution to this matter?
I have read elsewhere that Windows Update KB3156421 of May 18th could be a suspect.
