ExpressZip and Restoring Extract All Option

ExpressZip is one of products by NCH Software.  It usually comes with any NCH Software product, e.g., video or audio software.   Your system may not have any installation content or trace of ExpressZip including the registry entries.  However, there is usually a registry entry associated with "Extract with Express Zip" command, typically inside a user profile subkey of the HKEY_USERS hive.  Surprisingly the open command for "Extract with Express Zip" is set to using 7-zip command if you have 7-zip installed.

If you are using any product(s) by NCH Software, uninstalling them will usually restore "Extract All..." option but a reboot is required.  Or you may try and go to NCH Software to install ExpressZip, and then uninstall it.
