Cannot Update Windows Error 0x800f0831

Hello, JaronZH

Welcome to the Microsoft Community

Thank you for your feedback. I read the information you provided. You mentioned that you encountered a blue screen problem.

I noticed that the log you provided only recorded some brief problem information, but there was no other content that could be used to determine the problem.

Therefore, we hope that you can provide more information so that we can give more accurate suggestions.

You can obtain a small capacity dmp file by following the steps below, which will help you share this relevant dmp information:

Click "win+R" and enter "sysdm.cpl"

Enter system properties and click the Advanced tab

Find Startup and Fault Repair and click Settings

In Write debugging information, select Small memory storage

The following directory will become

"%SystemRoot%\Minidump"

You can remember this location. If you encounter a blue screen again, you can restart the computer and enter this location into the Explorer. You can see the .DMP file created in the folder. Provide this file to us through OneDrive and we will provide you with further suggestions after analysis.

Best regards

Let me know if this is enough information!

According to the information provided by the dmp file, the system has a SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (0x7E) error, which is a very common blue screen error. This error is usually caused by a driver or hardware failure, but it may also involve system file corruption or memory problems.

Some key information:

Bug Check Code: 0x7E (SYSTEM_THREAD_EXCEPTION_NOT_HANDLED)

This error usually indicates that a thread of the system encountered an unhandled exception in kernel mode.

Module causing the problem: BTHport.sys

This is a driver related to Bluetooth devices.

Log detailed analysis:

The log shows: "Memory manager detected 7 instance(s) of page corruption, target is likely to have memory corruption."

This means that the memory manager detected multiple page corruptions, indicating that there may be problems with the memory.

Based on the above analysis, you can try the following methods, which may help your current problem.

Reason 1: Run the Memory Diagnostic Tool to check if there is a problem with the memory.

Open the Memory Diagnostic Tool: Press Win + R, enter mdsched.exe and press Enter.

Select Restart now and check for problems, and wait for the diagnosis to complete.

At the same time, I also recommend that you can use a third-party tool such as MemTest86 for a more comprehensive memory test.

Reason 2. Bluetooth driver (BTHport.sys) problem

Open Device Manager: Press Win + X and select Device Manager.

Find the Bluetooth listing, right-click the device, and select "Update Driver".

Select "Search automatically for updated drivers". If Windows does not find a suitable driver, you may need to visit the official website of your device manufacturer to download and manually install the latest driver.

Reason 3: Run the System File Checker and DISM tools to repair possible system file corruption.

Press Win + X or right-click the "Start" button and select "Command Prompt (Admin)" or "Windows PowerShell (Admin)".

Enter and run the SFC command:

sfc /scannow

This command will scan all protected system files and replace damaged ones. This process may take some time, please be patient.

DISM can repair problems in Windows image files and is the next step when SFC cannot repair files.

Continue to use the command prompt with administrator privileges.

Enter and run the following commands:

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth

If you have tried the above methods and the problem still exists, we may need to check whether it is a hardware problem that caused the blue screen problem. If possible, I suggest you replace an external Bluetooth module and other memory sticks, and then test whether the blue screen problem still occurs. If the problem disappears, it may be a hardware problem that caused the computer to crash, and you need to replace these hardware.
