Bug with OperationStatusWindow (progress dialog) on ​​Windows 11 24H2 – solved!

Under Windows 11 24H2 (from May 2025), a serious bug occurs in the Windows shell: When file operations are performed with `IFileOperation`, the progress dialog (`OperationStatusWindow`) appears only on the first call - all subsequent calls no longer show a dialog , even if the actions are performed correctly.

🛠️ FAQ: Progress dialog (`OperationStatusWindow`) appears only the first time – Bug in `IFileOperation` on Windows 11 24H2

1.) 💥 Example for reproduction

C++-Code:

int TestFileOperation ()
{
IFileOperation * pFileOperation = nullptr;
HRESULT hr = CoCreateInstance ( CLSID_FileOperation, nullptr, CLSCTX_ALL, IID_PPV_ARGS ( &pFileOperation )) ;
if ( FAILED ( hr )) return 1 ;

CComPtr<IShellItem> psiFrom = nullptr;
CComPtr<IShellItem> psiTo = nullptr; // Customize example paths!
SHCreateItemFromParsingName ( L "v: \\ Microsoft Visual Studio" , nullptr, IID_PPV_ARGS ( &psiFrom )) ;
SHCreateItemFromParsingName ( L "d: \\ temp" , nullptr, IID_PPV_ARGS ( &psiTo )) ;
if ( psiFrom && psiTo )
pFileOperation->CopyItem ( psiFrom, psiTo, L "Microsoft Visual Studio" , nullptr ) ;
pFileOperation->PerformOperations () ; // the progress dialog appears only the first time
return 1 ;
}

2.) Repeated call with waiting time:

TestFileOperation () ;               // ✅ progress dialog appears
MessageBox ( 0 , 0 , 0 , 0) ;            // manual interval
TestFileOperation () ;               // ❌ no more progress dialog
Sleep ( 5000) ;                       // additional time interval
TestFileOperation () ;               // ❌ still no dialog
