Microsoft has confirmed that a recent update, with the catchy title KB 3004394, is causing a range of serious problems and recommends removing it.
It was first flagged by AMD’s Robert Hallock who noticed that the update blocks the installation or update of graphics drivers such as AMD’s new Catalyst Omega. Nvidia users are also reporting difficulty installing GeForce drivers.
Hallock recommended manually uninstalling the update, advice now echoed officially by Microsoft.
However, the update does not just kill off graphics drivers. Microsoft’s Answer Forum has dark mutterings that USB 3.0 drivers are broken and User Account Control prompts have gone haywire. Microsoft has acknowledged that it even prevents the installation of future Windows Updates.
The Windows Defender service has been disabled by the update.
This is the third time in three years Microsoft has issued software and firmware updates to their Xbox platform which have “bricked” the consoles. In August 2014 and April 2013 PC updates caused widespread Blue Screens of Death.
