Microsoft just released the September 2019 Patch Tuesday updates.
The new updates for all major Windows 10 versions come with some security improvements for Microsoft Edge, Internet Explorer, network technologies and input devices.
KB4515384 already has some weird bugs
The tech giant also addressed some vulnerabilities in some of the versions. Despite the fact that the updates were just released, some Windows 10 users are already having issues installing them.
After the USB HID device issue after September 10, 2019—KB4515384 (OS Build 18362.356) windows update, my HID device is no more recognized. It is listed by the usbview.exe application but the application I use to manage this device cannot see it.
And here’s the OPs screenshot:
The same user reported another weird issue with Device Manager:
I also notice that in the Device Manager a libusb-win32-devices item containing my device is now listed
If you’re in the same situation, you can try to rollback the windows update to a previous version to check if KB4515384 is causing the problem.
Update error 0xe0000100
Other users complained error 0xe0000100 is preventing them from installing the update.
Cumulative update KB4515384 fails to install with error 0xe0000100. Last month, cumulative update KB4512508 gave the same error. Was really thinking this month would be better. Manually downloading the updates gives the same error.
The weird part is that the Upgrade Assistant says the system is up to date. This could be a server-related error. Waiting for a few hours before making a new update attempt could solve this problem.
Start Menu and Search still don’t work for many
After a set of problems with Start Menu and Search, Microsoft acknowledged the problems and said that will be fixed with the next cumulative updates.
I am getting: Critical Error. Your Start menu isn’t working. We’ll try to fix it the next time you sign in.[Sign out now] I looked everywhere but couldn’t find a fix. SFC and friends did not help. Reregistering the Start Menu using Powershell did not help. The problem goes away if I uninstall the update but obviously that’s not a long-term solution
While for others, Search still doesn’t work and programs are not opening:
Installed the updated on a PC with version 1803. After the update, some programs are not opening. Tried from the start menu and desktop icon and they will not open.
It is possible that this is related to a faulty installation of the update. You can try to manually install KB4515384 and check if the problems persist.
BSOD and USB errors after updating to KB4515384
BSOD are quite common when it comes to new Windows 10 updates. When Windows 10 v1903 came out, it also had a lot of BSOD problems.
It seems that KB4515384 is also plagued by them. Some users are complaining about BSODs in the new update:
BSOD within a few minutes on 1903. Neat.The CU today. Blue screened while browsing the web
If you’re facing the same issues, you might want to take a look at this guide, as it may help you solve your problem.
Weirdly enough, some users are complaining about USB errors that affect KB4515384:
somehow this update disabled my keyboard with some usb errors”Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor failed.”
The issue might be related to your drivers. Sometimes, new updates replace your drivers with the default drivers from Windows 10.
If you encounter the same problem, we recommend that you manually update your drivers to the latest version by following the simple steps from this guide.
Latency issues after installing the update
This is not the first time when Windows 10 v1903 suffers from high latency issues, and this is pretty annoying because it can cause stuttering, audio dropouts, and FPS problems in games.
Here’s how one user is describing the problem:
this update broke again ntoskrnl.exe latency issues, it keeps jumping back up to over 710ms for me while it was fine in the previous os build 18362.329 (august optional update) with 0,50ms. Also ndis.sys is still around 400ms, not happy about this update at all.
Other users are reporting 100% CPU usage in some games:
ust broke something else for me lol. 100% CPU usage in some games according to task manager but not third party tools like HWINFO, and CPU-Z where they show 70-80%. 8700k/2080ti/32GBs RAM
The latency issue can affect games, as well as your desktop in some cases. For now there is no known resolution.
If you bump in to the same problem, we recommend that you rollback your Windows to a previous version. You can do so by going in to Settings > Update & Security > Recovery.
Under the Go back to the previous version of Windows 10, click on Get stared and follow the on-screen steps.
The rollback solved the problem for many, and it should solve it for you too. If the rollback was successful, you’ll have to block Windows from automatically updating your system by following this useful guide.
Nvidia graphics card problems
After installing KB4515384, some users are experiencing driver problems:
I literally just installed the newly released NVIDIA driver 436.30 non DCH, then Windows updates decides to forcefully install the older 436.15 DCH along with the cumulative updates today.
While for others, the graphics card seem to be unplugged and Windows doesn’t see it:
Hi, I have a problem. My graphics card which is an Nvidia GTX 1660 Ti is listed by the system as unplugged after I had downloaded and installed the newest windows update (KB4515384) which comes with NET. framework update KB4514359 and Security Update for Adobe Flash Player KB4516115. I did not do anything to the physical card, but the system did not detect it and said that I have to re-plug the card. Can anybody help me? I tried to remove all instances of the card by uninstalling, but I can’t seem to get it back.
This is a pretty annoying problem, and it might be caused by your graphics card drivers. You can try to solve it by installing the latest driver available from the manufacturer’s website.
If you don’t know how to update your Nvidia graphics card, we’ve prepared a useful guide that will help you do it with ease.

Performance and language issues
It seems like for many Windows 10 users, KB4515384 slows down their PCs:
I have a Dell Laptop about 2 years old – Intel , lots of RAM with SSD drive. Laptop was running super fast – fast boot, just everything was great, until this latest KP4512941 update.
This is a problem of optimization and you should solve it by running sfc /scannow and DISM. After that, your Windows 10 PC should work properly.
Other users are complaining about the language bar and the inability to use it:
After (automatically) installing 2019-09 Cumulative Update for Windows 10 Version 1903 (KB4515384), the language bar disappeared after login. On the login screen it shows normally and can be used to switch languages. Running ctfmon has no effect. In addition, in the Language options, when choosing ‘Add a keyboard’ for Chinese (Simplified, China), all of the two keyboards are gray and cannot be added. Another new language (tested Chinese Traditional) can be added but when adding a new keyboard all options of keyboards are also gray.
The only solution for now is to uninstall KB4515384. After uninstalling the update, things should go back to normal.
