Anandtech reports that AMD sends word this evening that they are advising users to remove update KB3004394, which was released as part of this week's Patch Tuesday, due to driver installation issues this update is inflicting.
The update, designed to update Windows’ root certificate store, has apparently been causing havoc on some Windows 7 configurations. In AMD’s case what they are finding is that the update prevents the installation of new graphics drivers on affected systems, with both AMD and NVIDIA drivers refusing to install. More broadly, Infoword is reporting that KB3004394 is also being blamed as the culprit behind certain issues affecting Windows Defender, Task Manager, and other software.AMD Recommend Uninstalling KB3004394
At this point this looks like the update only affects a small number of systems – Windows 8 is not affected, and even then most Windows 7 systems appear to be fine – but Microsoft has not taken any chances and has pulled the update. In the meantime for those users that are affected, uninstalling the faulty update reportedly fixes the issue.
