Windows.Storage.Provider.StorageProviderSyncRootManager.Register returns HRESULT_FROM_WIN32(ERROR_INSUFFICIENT_BUFFER)

[PetrMinar]

The documentation should mention that there is a limit to the maximum length of StorageProviderSyncRootInfo::Id. Deep inside the Register function is this code:

StringCchPrintfW( 
    DestBuffer,
    260,
    L"%s\\%s\\CustomStates\\%d",
    L"Software\Microsoft\Windows\CurrentVersion\Explorer\SyncRootManager",
    L"... StorageProviderSyncRootInfo::Id ...",
    1);

When the ID is longer than 174 characters the function fails with mentioned error and leaves "semi-registered" storage provider that cannot be easily unregistered.
