8 Ways to Fix the Worker Invalid Error in Windows 10

WORKER_INVALID and other Blue Screen of Death errors will restart your computer whenever they appear. This is to prevent damage to your PC.

This error can be rather serious, keeping your system from adequately booting and causing you to get stuck into a restart loop. The causes of the error vary but mainly down to faults with hardware.

Irrespective of the cause, we have gathered eight surefire fixes to help you solve the issue for good on Windows 10/11.

What does Worker Invalid mean?

The Worker Invalid error is usually caused by broken or corrupted system files. You can fix this with a dedicated BSoD fixer or the built-in system repair tools.

Also, it can be caused by outdated PC or drivers. Updating your operating system and drivers should do the job here.

What’s the BSOD meaning?

BSOD stands for Blue Screen of Death, and is an error that crashes the OS. It’s also called a Stop error because a Stop Code is listed when users encounter it.

The error usually occurs due to a fatal problem with the PC, and the underlying causes vary a great deal. From issues with the hardware to software, identifying what’s causing the problem in a specific case can itself be a tricky task.

4. Finally, click the Install now button.

To ensure that your PC is running without any problems, we strongly advise that you use Windows Update to download the latest updates.

Many of these updates bring new features and security improvements. There are also various bug fixes for issues related to hardware and software, like the Worker Invalid error, since BSoD issues are often caused by hardware or software issues.

It is essential that you restart your PC after the update to effect the changes.

4. Update drivers

4.1. Update drivers manually

Outdated drivers are among the major causes of the Work Invalid error. This is because Windows 10 relies heavily on drivers to work with your hardware.

Aside from using the built-in updater, you can visit your hardware manufacturer, locate your device and download the latest drivers.

Remember that you might have to update drivers for all major hardware components to fix this error.

A few users reported that the Etron USB3.0 Host Controller driver is causing this error, so if you have this device available, be sure that you update it first and then move to other hardware components.

4.2. Update drivers automatically

Searching for drivers on your own can be time-consuming. So, we advise you to use a tool that will do this for you automatically.

Using an automatic driver updater will save you from the hassle of searching for drivers manually, and it will keep your system updated with the latest drivers.
