Anyone who knows how to disable logs with “Click-To-Run General Telemetry” entries?

Posted by jpluimers on 2018/11/05

Both in %TEMP% and %Windir%\TEMP, a lot of log files named %COMPUTERNAME%-yyymmdd-hhnn.loghaving entries named Click-To-Run General Telemetry appear.

Anyone who knows how to disable this logging?

I think they are related to Office 2016 installed through Office 365.

Disabling the Click-To-Run Monitor scheduled task is not a good solution, as it will also Office disable update notification: [WayBack] MS Office 2016 – Click to run logs | MalwareTips Forums

IPv4 to IPv6 conversion on a load balancer causing rare packet loss

Posted by jpluimers on 2018/11/02

Nice find on not so nice packet conversion: [WayBack] Fun with IPv6 We were investigating packet loss. The loss rate was very low (smaller than 1 of 1000) but as UDP was used, it caused rare but noticeab… – Martin Seeger – Google+

You are not Google (use UNPHAT) – The Isoblog.

Posted by jpluimers on 2018/11/02

and you are not Amazon or LinkedIn either.

Next time you find yourself Googling some cool new technology to (re)build your architecture around, I urge you to stop and follow UNPHAT instead:

  • Understand problem
  • eNumerate candidate solutions
  • Papers of candidates
  • Historical context of candidates
  • Advantages/disadvantages
  • Think!
