Question

Kernelbase.dll errors after windows 10 updates

Dave Nelson 15

We have 5 computers that can no longer run the photo or calculator apps. They generate a kernelbase.dll error and this appears to have happened after windows updates.

Got one affected PC as well. The issue is discussed in this reddit post as well: https://www.reddit.com/r/WindowsHelp/comments/1abvlpm/calculator_and_photos_app_broken_in_win10/ Seems that some Windows update has broken several Windows apps for computers that are still running 2-core CPUs. Latest advise is to update the apps from the Windows store to fix the issue.

I recently had issues with ActiveX (Autodesk Inventor) having out of memory issues (more of a buffer than system memory) but I was not able to resolve the issue. This is using .NET Framework and multiple release levels where attempted using C# and I couldn't find any specific system errors until I tried it with VB. When I checked the Event log, I finally found a related Application Error that reported KERNELBASE.DLL as the error. Looking at the file properties, this was modified 3/4/2024.

Hello Kernelbase.dll errors can occur due to various reasons such as corrupted files, system updates, or software conflicts. Here are some methods you can try to resolve these issues:

Run System File Checker (SFC): System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. To run it: Open Command Prompt as an administrator. Type sfc /scannow and press Enter.
Run DISM (Deployment Image Servicing and Management): DISM is a command-line tool that can be used to service and prepare Windows images, including those used for Windows PE, Windows Recovery Environment (Windows RE) and Windows Setup. To run it: Open Command Prompt as an administrator. Type DISM.exe /Online /Cleanup-image /Restorehealth and press Enter.
Reset the Apps: You can reset the Photo and Calculator apps from the Windows settings. To do this: Open Settings and go to Apps. Find the app in the list, click on it, and select Advanced options. Click on the Reset button.
Update the Apps: Check if there are any updates available for the apps in the Microsoft Store.
Reinstall the Apps: If the above methods don’t work, you can try reinstalling the apps.

I have a similar issue, but in Windows 11. I have my own application that previously worked just fine. Now, the same code causes an exception in kernalBase.dll:

KernelBase.dll!MultiByteToWideChar()
comctl32.dll!ProduceWFromA()
comctl32.dll!TV_InsertItemA(struct TREE *,struct tagTVINSERTSTRUCTA *)
comctl32.dll!TV_WndProc(struct HWND_ *,unsigned int,unsigned__int64,__int64)
user32.dll!UserCallWinProcCheckWow(struct _ACTIVATION_CONTEXT ,__int64 ()(struct tagWND *,unsigned int,unsigned __int64,int64),struct HWND *,enum _WM_VALUE,unsigned __int64,int64,void *,int)
user32.dll!SendMessageWorker()
user32.dll!SendMessageInternal(struct HWND *,unsigned int,unsigned __int64,__int64,int)
user32.dll!SendMessageA()
user32.dll!SendDlgItemMessageA()

The exception occurs when sending the TVM_INSERTITEM message to a TreeView control:

HTREEITEM newNode = (HTREEITEM)SendDlgItemMessage(hDlg, IDC_PRESET_TREE2,TVM_INSERTITEM, 0, (LPARAM)&tvinsert);

I have also created a separate application, using the same code to populate a TreeView control, and this works without issues, which would indicate that my system libraries are ok.The last build of my application that worked was on April 9th. I noticed this error on June 7th. There were most probably both windows and VisualStudio updates during this period, but I have no history of updates as I had to completely install Windows 11 due to a failed windows insider update.

What could cause such an exception where there has been no code change, but only windows and VisualStudio updates?
