Security, Quicktime is No longer supported
I can't run QuickTime anymore on my machine.
Two critical vulnerabilities have been found in QuickTime for Windows. The vendor, Apple, has recently confirmed that they will no longer fix security issues with this product, leaving any systems running this software vulnerable to attack.
What We're Doing
We have created a domain-wide rule that will disallow QuickTime from running on Windows systems that are joined to UOFI Active Directory.
The rule was applied on May 23, 2016.
When this rule is applied,
customers who try to run QuickTime or open a QuickTime file will receive an
error message that this program is blocked.
What You Can Do
Remove QuickTime for Windows
from all machines in your unit, and switch to alternatives like Windows Media
Player or VLC.
