As with the October update, IDCRL is no longer listed as a pre-req. I’ve left it here scratched out just for the time being…


The Install Process

I’ve converted to using Tom’s great “install-hotfixes” PowerShell module to install my updates these days. Here’s the output. Note that I’ve dropped ALL of the pre-req’s in the one folder (including the old ones I already believe I have installed) and am letting them fight it out:



Alas, yes – although the KB says no. The MSO update set the reboot flag apparently. (Click the image for a more legible view).

  1. 3009719 Lync 2013 freezes when a toast notification of a call appears

    I started to be happy, as I am struggling such an issue on all of our company-imaged laptops (cannot start or receive any kind of calls, all such attempt immediately freezes the Lync2013 application, it has to be killed from TaskManager). So I visit the KB article to see under what circumstances the issue surfaces. The answer: NADA, thats not my business. Pathetic the quality of B articles and issues descriptions MS is releasing in the last 2-3 years.
