Solution

  • I think you need to modify registry.

    1. Set NavPaneExpandToCurrentFolder to 0
    2. Do whatever you want
    3. Restore existing value of NavPaneExpandToCurrentFolder

    Use following code to modify registry:

    using Microsoft.Win32;

     

    const string key = @"HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced";
int enabled = 1; // 0 to disable
Registry.SetValue(key, "NavPaneExpandToCurrentFolder", enabled, RegistryValueKind.DWord);
