Microsoft is again encountering serious problems related to one of its updates. In this case, these refer to Windows 10 KB4556799 , a recently shipped patch that has become a serious problem for some users.
As we already told you just a few days ago, this patch corresponding to the last Patch Tuesday of the firm, began to give problems from the beginning. This was released for versions 1903 and 1909 of Windows 10 , and some were unable to install it from day one. Say KB4556799 is a major security update that the firm recommended to install as soon as possible. Well, with the passing of days, now it is being seen that it also causes audio problems and temporary loss of personal data.
KB4556799 Windows 10, with serious problems
Thus, users using Windows 10 May 2019 Update or November 2019, report that the mentioned update comes with a wide range of problems. Included here are a failing audio adapter, a temporary user profile, BSOD blue screens, and installation problems. At the same time, saying that these problems seem to vary from one computer to another and does not affect all installations of Windows 10.
Something that has been seen is that the patch restarts all audio driver settings, and even removes the Realtek driver. Others also noted that their audio devices do not send sound when the update is installed. Therefore, all audio suddenly stops working on the PC. In principle the most effective solution for this is to uninstall the update so that the audio returns.
Among the failures detected at this point, we can find playback problems, sound distortion, audio devices sending sound, or even passing it simultaneously through the earpiece and speakers.

Therefore, another possible solution is to right-click the volume icon on the taskbar. Here we open the Sound Settings and click on Sound Control Panel.
Then in the Playback tab we right-click on the Realtek speakers to open Properties. Thus, in the Advanced Options tab we disable Audio Enhancements . Similarly, changing the audio settings of Windows 10 so that the quality is 16 bits, could also solve the problems.
In the event that none of this works, the best we can do is uninstall the Windows update completely. This is accomplished from Settings / Update & Security / View update history / Uninstall updates.
Other problems detected in Windows update
But these are not the only problems with updating KB4556799. And it is that some people claim that it has deleted their data and that files, images or personal documents are missing. At this point, we will say that there are users who warn that after updating, all personal files on the computer were deleted. Obviously this is something very alarming for most. Specifically, we mean that your own data is missing and that all the operating system settings return to the default ones.
What has been discovered is that this is because Windows 10 loads a temporary user profile during the update installation process. Thus, it continues to use it instead of the normal user profile. As a result, users notice that their desktop customization, taskbar applications, or folder files like Documents and Pictures disappear.
You have to know all these files are still there, but in the main user profile , also for this there is still no solution that works. Therefore the best thing here is to uninstall the problematic update, as we showed you previously.
