When Windows Explorer Shell Extensions are ported over from Windows XP to Windows 7 they don’t work with 64-bit version of Windows 7 because the original shell was developed for 32-bit OS only. We occasionally come across such shell extensions that lack 64-bit support. Even though the shell extension has installed successfully, you won’t find it in the Windows Explorer context menu. There is a small hack that allow users to convert the Windows Explorer from 64-bit(x64) to 32-bit(x86), but it is too risky.
Half Shell is a tool that can open folder in 32-bit inside Windows Explorer so that you can finally use the 32-bit shell extensions. This method is more efficient, safer, and easier than hacking the registry.
We all know that pressing Ctrl+Enter hotkey will open a selected folder in new window. Half Shell adds a new hotkey, which is Shift+Enter. Pressing this hotkey will open the folder in a new window but in x86 mode rather than x64.

Now you can work with all 32-bit shell extensions inside this folder. The app has no interface but sits silently in the system tray which can be closed anytime. It is a portable tool which works on Windows Vista 64-bit and Windows 7 64-bit OS only.

It will automatically free up all unneeded memory after the folder has opened completely in 32-bit. Thus, it is completely safe to use without worrying about the memory usage
