Secure QuickTime installation tutorial

Monday September 5th 2016

As you may have heard, QuickTime has some security vulnerabilities, and there have been recommendations to uninstall it, since Apple is no longer updating it. Unfortunately, there are a lot of professional programs that need QuickTime. For example Adobe After Effects, GoPro Studio, and Sony Vegas. We have written a tutorial that shows you how to install only the essential components, and skip the insecure ones (such as the web browser plugin).

Windows 10 Build 14393 "Anniversary Update"

Wednesday August 3rd 2016

Microsoft has released a new version of Windows 10 yesterday. This is a major update and it is installed as a full upgrade of Windows. This means that a lot of things are reset to the defaults of Windows. This includes a few settings related to multimedia playback, such as thumbnails, file associations, and certain codec tweaks.

For an optimal user experience we recommend that you re-install the (latest version of the) codec pack after updating Windows. That way all your preferred settings can be re-applied.
