Fix Unexpected Store Exception on Windows 11: Are you experiencing system crash due to mysterious Unexpected Store Exception error? This is a blue screen error caused by an internal error in the Windows kernel memory. Currently, there is a main method to fix the Unexpected Store Exception in 11, as Microsoft has also acknowledged. We also discuss some additional troubleshooting tips.
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.
This kernel memory module manages the RAM used by several core components in Windows along with device drivers. The Windows operating system uses it to talk to the device’s hardware.
Fix Unexpected Store Exception on Windows 11
1] Debug with WinDbg
Download and install WinDbg
After downloading the executable, install it on the system. In step 2 of the installation to debug your Windows software, you don’t need all the features of the Windows SDK. Just select Debugging Tools for Windows and uncheck everything else.
- Go inside the installation directory and find the WinDbg executable. Double-click to launch the WinDbg executable. From the File->Open Executable menu, you can view any executable on your PC.
- Locate the “Notepad.exe” file on your system, which is usually located in the System32 folder. Open this executable with WinDbg.
- To test this debugger, type .sympath srv * in the WinDbg command line located at the bottom.
- The results will be displayed in the Notepad window. Here we see an icon search path that tells WinDbg where to look for symbol files (PDBs).
Symbol search path is: srv*
Expanded Symbol search path is: cache*;SRV
Option 1: Create a user-mode dump file
- Open Settings on your PC. On the right, scroll to the bottom and select About.
- Select Advanced System Settings.
- This will open the System Properties window.
- Select the Advanced tab at the top and click Settings under Startup and Recovery.
- A new Startup and Recovery window will open.
- Record the location of the Dump file. It can be easily overridden without any problems.
- Now go back to the WinDbg command line and enter the following to create a user-mode dump file.
.dump [options] FileName
- Instead of “?” you will have to import mf or ma which refer to multiple dump file types. Also replace FileName with the previously used Dump file path.
- 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.
Option 2: Use the command! Analyze Extension
To find the root cause of the “Store Exception” error, you can use another WinDbg command called “!Analyze” extension.
- Go back to the WinDbg command line and copy paste the following:
!analyze [-v] [-f | -hang] [-D BucketID] !analyze -c [-load KnownIssuesFile | -unload | -help ]
- Exception analysis has begun. If any files crash on your PC, they will be logged.
- Delete those files or uninstall any programs associated with the “Store Exception” error. If there are no problems, you will not see any results.
- 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.
Launch Windows Memory Diagnostic from the Windows search menu.
As soon as the application is launched, you will be asked to restart the device and check for memory problems.
You can restart your PC immediately or schedule a diagnostic any other time.
4] Find the Exclamation Mark in Device Manager Hardware
Open Run and type devmgmt.msc. Under each hardware device, look for an exclamation mark (!). If you have any faulty external webcams, SD cards, pen drives or external drives, remove them first.
5] Perform System File Checker and ChkDsk
Open Run and type sfc /scannow. If any system-repair reboots are pending, go ahead and run SFC again.
You can also use the ChkDsk utility to repair any problems in the hard disk.
