hlp4win11 - Legacy HLP file support for Windows 11 and 10

Microsoft has phased out support for these files, so third-party viewers are often the best route.

To restore support for legacy HLP (Help) files in Windows 10 and Windows 11, you can follow these steps. Since Windows 10 and 11 have disabled the Windows Help system by default, you'll need to manually enable or install the necessary components.
