WORKER_THREAD_RETURNED_AT_BAD_IRQL with the digital code 0x000000E1 indicates that the workflow has completed and returned with IRQL> = DISPATCH_LEVEL.

Work at the computer may be interrupted by the blue screen of death, and the code 0x0000001e will be indicated first in the description of the cause of the failure.

To fix the problem, we recommend that you follow these steps:

Review the description of the problem. After alphanumeric designations, the process that caused the BSOD can be indicated there. This may be a system service or a driver file. Explore this reason. Make sure system files are not corrupted. Remove the driver, and to use the hardware further, use a different version of the driver.

Disable caching and shading in the BIOS (UEFI). It is also rational to install the latest firmware version on the motherboard.

Verify that the computer does not have any malware. This is most rational to do when connecting a disk drive to another PC.

For Win 7 and Server 2008 R2, use this explanation from Microsoft.

Inspect the technical condition of the drive and RAM.

Uninstall applications that were installed 6 or were pre-installed before the blue screen of death occurs with error 0x0000001e.

4 Recommendations for the Elimination of BSoD:

1. 0x000000E1: WORKER_THREAD_RETURNED_AT_BAD_IRQL may appear due to errors in the code of the operating system itself.

Installed the latest update package (Service pack) and the constant updating of the system will save a lot of errors.
2. If 0x000000E1: WORKER_THREAD_RETURNED_AT_BAD_IRQL appeared after the newly installed device driver or program. It is necessary to roll back the driver to an earlier version. With programs, things are easier, removing them will eliminate the cause of the failure. The “Run Last Known Good Configuration” option may be useful.
3. If 0x000000E1: WORKER_THREAD_RETURNED_AT_BAD_IRQL began to appear after you have connected a new device to the system, then you need to check it for compatibility with your operating system. If the device is compatible, then you need to download the latest drivers from the official website of the manufacturer and install them. If the latest drivers are installed, you need to install an earlier version of the drivers. If the device is incompatible with the operating system, then it is necessary either to change this device or to change the operating system that supports this device.
4. Very often the cause of the appearance of 0x000000E1: WORKER_THREAD_RETURNED_AT_BAD_IRQL is a malfunction of the RAM. To test it, you can use testing programs, such as memtest86+.
