Cumulative Update KB4515384 Causing Headaches for Windows 10 Users

A Windows 10 cumulative update released on September 10, 2019, is causing problems for many Windows 10 Users. Microsoft acknowledges that cumulative update KB4515384 is causing audio problems as well as network adapter problems. Those who have installed KB4515384 are also reporting that the update breaks Action Center, and/or Windows 10 Start Menu and/or Windows search.

If this cumulative update causes problems for you, we recommend that you do one of the following. 

1. Use System Restore to restore your computer back to a point in time before you installed the update. To perform a System Restore, open a run dialog – Windows key + R – and type RSTRUI in the run box and press enter.

2. Uninstall the update and then hide it so it does not reinstall. See our tutorial here

We recommend using method #2 as it will prevent KB4515384 from reinstalling.

Cumulative updates differ from Windows Updates in a way that the latter is used to keep your Windows-based computer up to date with the latest patches. Cumulative Updates are rolled out as collective updates and include improvements and enhancements for the Windows 10 operating system. Windows Updates are released to keep Windows-based computers up to date with the latest patches.

Here’s more Windows 10 cumulative update KB4515384 from MS Poweruser:  

The Windows 10 KB4515384 cumulative update has proved to be quite buggy, with some compromising the Start menu and Windows Search, and others causing audio issues. Users have now reported on further issues that they’re experiencing with the update.


On Microsoft’s Feedback Hub, a user reported a bug that came with the update, that disables Ethernet or WiFi connectivity.


Cumulative update (kb4515384) causes the NIC to fail to enable with a code 10 error. Reinstalling network drivers from Intel or Windows Update sources does not resolve the issue. However removing the update through the ‘Programs & Software’ panel or using a recovery point set *before* the update fully resolves the issue.


Another user reported that their network adapter stopped working after they applied the update:


KB4515384 breaks ethernet and wifi adapters on my PC. Appears to create new devices as they’re labelled ‘#2’ and when exposing hidden devices in Device Manager the previously named devices appear. Uninstalling these / new or old drivers do not fix the issues (i.e. “ethernet unplugged” which it is clearly not). Only option was to uninstall this update.


Additionally, users have been unable to open Action Center after installing the update.

    All I can say is “thank you” for teaching us how to delay updates! I did this when I got the alert that it was going to be installed and delayed it for a week. After reading this article I will delay it again.

    I thought that Windows update back at the end of June 2019 caused my problem with my WIFI connection. I was needing to go into my Internet trouble shooter to get connected every time I wanted to connect to the Internet, This issue lasted for at least 1 1/2 months or so. Then it started working fine. But with this last update the WIFI started doing this again. It has been fine for the last couple of days now. By the way, the email I got from you about these issues could not find this page. I had to go into your site and click on the link in there in order to read about this.

      Sorry about the link trouble. We changed servers yesterday and the post not updated in time. It’s fixed now. You’ll see the correct link in the next newsletter (fingers crossed).

    So far I am having no problems. Should I wait to see if problems occur or just uninstall as a precaution. Also if Microsoft has a fix for this update should we go back and install original update ( in case this update had other things needed) and then install the fix. Looking forward for your insight on this matter.

      If you’re not having any problems there’s no reason to do anything. Keep in mind a few million users had problems with this cumulative update. But there are 100’s of millions of Windows 10 users, so the percentage is less than 10% of users. If you’re not one of the 10% you don’t need to do anything.

    Thank you for the information. I have removed & hidden the KB4515384 update, which caused the computer sound to stop. I could not find the download for the wushowhide.diacab to hide this update. Went to Microsoft Download Center, but could only find questions & answers about this download. Did find a link to the download, but it did not show a down load button. When you have time would you please check this out? Thanks for all the information & helpful advice you have sent our way.

    I guess I’m one of the lucky ones who did not have any problem at all. Nothing seemed to have gone wrong with my laptop so far.

    I must have 3 magic computers… Neither desktop in my house or my surface pro 4 have ever had any issues from an update except for once when 1 of the computers was in the fast ring preview program so that doesn’t really count.

      Only a small fraction of users are affected – as pointed out in the article. But 2% of 400 million Windows 10 users is 8 million people. That is about the population of New York City and more than the population of Indiana. No magic computers at all. Microsoft does not very often admit their updates are buggy, the fact that they admitted it time means it affected more than a handful of users. Your odds of being affected are slim even with 3 computers. The purpose of the article was to inform. Your chances of being affected by this even with 3 computers are 6 out of a hundred.

    I had installed this update then noticed that I was having troubles with my internet so I did as you posted and uninstalled it and downloaded the program to hide it. My internet seems to be back to what it was before I installed this update. Thank you for helping us out!! A Million Thanks!!
