What is the Unexpected Store Exception?

The Unexpected Store Exception error is caused by multiple hardware and file integrity issues related to the kernel memory module. The error is also known as UNEXPECTED_STORE_EXCEPTION and has the value 0x00000154 which refers to the stop code, a special type of blue screen error.

  • Your exception analysis has begun. If there are any exception errors on your system, they will be highlighted here. Problem files will be mentioned in the log and you will be able to take corrective action from there.
  • In addition to WinDbg, we can use another simple method to create a fake crash. It is called “NotMyFault” by SysInternals. Download the zip file and extract it.
  • Then, click the NotMyFault app to launch a new window where you can simulate the crash. Close all other applications so that corrupted memory is not written to disk after Reboot.

!analyze [-v] [-f | -hang] [-D BucketID] !analyze -c [-load KnownIssuesFile | -unload | -help ]

  • Bucket ID refers to the exact event ID connected to the Store Exception error.
  • As soon as you notice the blue screen on the laptop screen, you can see the Bucket ID highlighted prominently. If you missed it, you can find the same Bucket ID from the Event Viewer in Windows 11.
  • While WinDbg is the best method for debugging Unexpected Store Exception, if you don’t want to learn to program, Microsoft suggests some other options.

2] Reinstall or Recover Windows

If any of the blue screen errors are caused by some recent events, you can perform a simple reinstall or System Restore to bring your Windows device back to an earlier configuration.

3] Windows Memory Diagnostic

You can use the Windows Memory Diagnostic application to deal with bad parts of memory that can cause the Unexpected Store Exception problem.
