is a kernel driver. If the UMBus Enumerator Driver fails to load or initialize, the error is recorded into the Event Log. Windows 7 startup should proceed, but a message box is displayed informing you that the umbus service has failed to start.

is a kernel mode driver. If UMBus Enumerator Driver fails to start, the error is logged. Windows 10 startup proceeds, but a message box is displayed informing you that the umbus service has failed to start.

UMBus Enumerator Driver is a kernel device driver. In Windows 10 it is starting only if the user, an application or another service starts it. If UMBus Enumerator Driver fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the umbus service has failed to start due to the error.

3. Close the command window and restart the computer.The umbus service is using the umbus.sys file that is located in the C:\Windows\System32\DriverStore\FileRepository\umbus.inf_x86_8351669303b483f7 directory. If the file is removed or corrupted, read this article to restore its original version from Windows 10 installation media.

The name is quite mysterious, and this driver only seems to be present from Windows 10 onwards, and it might be behind a few specific performance issues. If you want to know the Microsoft Device Association Root Enumerator, be prepared for a slightly long-winded answer.

If disabling this enumerator helps your game performance, disconnect all legacy devices, re-enable the enumerator, and add them back one at a time until the performance issues return. Then, in the future, just unplug that hardware before playing.

The umbus.sys process is also known as User-Mode Bus Enumerator and is a part of Microsoft Windows Operating System. This software is produced by Microsoft (www.microsoft.com). An obsolete or defective version of umbus.sys can cause problems for your computer that can range from slowness to error messages such as these:

umbus.sys is part of Windows. The file umbus.sys is found in the C:\Windows\System32\drivers directory.The file size is 39,936 bytes.
If necessary, you can manually stop or start this driver in the Device Manager. The Device Manager can be found in Windows Control Panel under Hardware and Sound/Devices and Printers/Device Manager. The driver facilitates access to your computer's hardware and accessories.The Windows operating system requires this file. Umbus.sys has been digitally signed by Microsoft itself to guarantee its authenticity. This particular software does not appear as a visible window, but only in Task Manager. For this service - unlike Windows' own system services - there is no good description available.umbus.sys appears to be a file that was compressed by an EXE-Packer. This technique is often used by trojans to keep the file size small and also hamper debugging efforts. However, this in itself is not sufficient reason to presume malicious intent, since even well-intentioned, professional software producers take advantage of compressed files.For this reason, 0% of all experts consider this file to be a possible threat. The probability that it can cause harm is high.

If you see this file on your hard drive or in Windows Task Manager, please make sure that it is not a malicious variant. It's a fact that many trojans try to cloak their true identity by calling themselves umbus.sys. With the above information or by using tools like Security Task Manager you can determine if, in your case, the file is an undesirable variant.

After uninstalling, restart your computer. Then start Windows Explorer and see if there is still a folder with the name of the software under C:\Program Files. Be sure to check the Registry as well for remnants of User-Mode Bus Enumerator. To do this, start "Regedit", then look under "HKEY_LOCAL_MACHINE" > "Software" for User-Mode Bus Enumerator or the name of the producer. Always keep in mind that only a computer professional should ever directly delete entries in the Windows Registry.

If Windows not working quite right for you, or if startup is taking a long time, or umbus.sys is causing problems for you, a good Windows diagnostic tool may very well help. This is especially effective when it comes to older computers that have accumulated vast quantities of "garbage data" as the result of many software installs and uninstalls.
