HHReg

The Internet is filled with all sort of nice software solutions that are suitable for doing all sort of things on your computer. One of such applications is HHReg. It's used for registering HTML Help (.chm) files on an individual Windows computer.
It's packed with multiple features and tools that you can check out, aside from some settings that you can adjust.

Intuitive graphical interface with plenty of tools at hand

The application doesn't require you to complete a complicated setup before you can use it and it doesn't take long to install on your computer. It sports a really intuitive graphical interface with plenty of tools at hand.
Registration for HTML Help files is required since Microsoft issued a security patch for Microsoft Internet Explorer, disabling in general all HTML Help files that are viewed from a network drive.
HHReg removes this limitation by explicitly registering HTML Help CHM files in the Windows registry, making them available for viewing even when opened on network drives.

Register HTML Help files on your system

The first thing that you need to do after launching the application is to add files, folders and URL addresses which are registered and explicitly permitted.
You can also select the current security setting for HTML Help files, pick from local machine, local intranet zone, trusted sites, Internet zone and restricted access zones. Block the ones that you won't want to provide access to.

More features and tools

If you set the access to the Internet zone or Restricted sites zone will enable all CHM files from any network sources or even from restricted sites. But this will compromise the security of your computer.
It comes with a section that displays HTML Help and Winhelp files registered with a path. It displays their location on your machine and other details.
All in all, HHReg is a really nifty software solution that you can use for registering HTML Help (.chm) files on an individual Windows computer.
