Last week, Microsoft rolled out a series of updates aimed at fixing a major CPU security vulnerability affecting virtually all Windows computers.

Windows 7KB4056894is one of thosepatches, but judging by user reports, the update caused more harm than good. Many users complained that the update caused their computers to stop working.

As a quick reminder, another major update triggered similar results. Windows 10 version 1709 KB4056892 turned many computers into simple pieces of decoration. Read more about it inthis round-up article.

So, if you’re planning to update yourWindows 7computer soon, read this article to learn what are the most common KB4056894 bugs reported by users. Maybe you’ll change your mind and postpone installing the updates, although this means making your PC vulnerable to the latest CPU cyber threats.

Windows 7 KB4056894 issues

1. BSOD and error 0x000000C4

By far, the most frequent KB4056894 bugs is the annoyingBlue Screen of Death. Judging by the number of views that this thread got on Microsoft’s forum, there must be tens of thousands of users experiencing this problem.

After installing the latest Windows updates and rebooting, I got the following error:*** STOP: 0x000000C4 (0X0000000000000091, 0x0000000000000000, 0xFFFFFF80002C4EFC0, 0x0000000000000000) I could not boot into Safe Mode. I was able to boot into the recover console and uninstall the latest update that was still in the “Install Pending” state

Again, it seems that thisissue is prevalent for AMD computers, and especially those powered by the following chips:

Somehow, the latestWindows updatesappear to be incompatible with AMD CPUs. Although users have been reporting these problems for several days, Microsoft and AMD have yet to issue any comments.

This piece of advice coming from aWindows 7user who already encountered many issues after installing the update perfectly resume the general user opinion:

Microsoft should update MS KB article 4056894 acknowledging the BSOD problem when KB4056894 is installed on affected AMD CPUs, which they have not yet done. In the meantime,Win7users using any AMD processor (old or new) should avoid installing the KB4056894 update until MS issues a revised patch or a new one with a different KB number to address the blue screen crashes.

2. Computers won’t boot

OtherWindows 7users warned that installing KB4056894 may lead toboot up issues. More specifically, the OS fails to boot up with various error codes displayed on a black background, but the good news is that you can fix the problem.

3. The screen goes black

In some case, theupdateseems to crash the display driver. Users report that every 15 minutes, the screen goes black without affecting the running programs. In most cases, the problem goes away after a few seconds.

I recently installed KB4056894 […] Prior to doing so, my Dell Inspiron 1420 laptop runningWindows 7Pro had been working just fine. Since theupdatewas installed yesterday, every 10-15 minutes, my screen goes entirely black for about 3-5 seconds, as if the display driver is crashing and restarting. It doesn’t appear to affect any of my running programs, nor does it crash the computer. But clearly, it should not be causing the display to goblack.

4. Software failure

If some of your programs recently stopped working after you installed the latestWindows 7 updates, you may want to uninstall the respectivepatches.

While not as frequent as the three issues listed above, this problem is indeed affecting quite a few users.

I am runningWindows 7Professional and the only recent Windows update was: 2018-01 Security Monthly Quality Rollup forWindows 7for x64-based Systems (KB4056894).
