Though we don’t normally report on Windows updates, we’ll make an exception on this one. 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.

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.

    Honestly, I probably would have ignored the post other than I saw it had something to do with AMD. I had been fighting my system trying to get the latest display drivers updated. The whole thing kept hanging. I'm an AMD fan (have 2 in crossfire), but when their driver fails to install I look to them first. I'm sure I would have found the correct information eventually (that it's a MS problem), but this saves me a few minutes looking up problems on the AMD side. Reply

    Hey Ryan,
    after all the hotheads that responded to your goodwill post, do you now think you wish you never bothered. Lol

    To me it makes them look better. Oh look they care enough about the customers to inform them of potential issues & a workaround without hiding or making up some lame excuse. That's some top quality customer service right there. Reply

    Unfortunately not everybody cares about AMD's customer centric approach. Many take advantage of that to attack the company. Reply

    Don't be a prick. AMD and Microsoft are referenced on the title because it's a recommendation of theirs to remove the said update. By the way... do you have any money on AMD to react so bad to a thing like this or you just fancy them? Reply

    Don't be a prick yourself moron. Ryan gave an answer and everything is OK. If you are trying to pretend to be his layer, you are a little too late, don't you think? And if you had half a brain you would understand that AMD is vital to everyone, not only to those who have money on them or fancy them. Reply

    Three computers suddenly lost most of their Microsoft signatures. Two I re-installed already. Thank you update KB3004394 :/ Reply
