Reader Preferences (2017 DC) - Registry location

We have several Preferences in Reader that are required for our apps to work correctly.

Several times per year, many of them will lose their preferences and be reset to defaults and we're not sure why.

I'd like to know why this is happening, but I could work around it if I could enforce those preferences through registry settings.

At the very least, I'd like to be able to make a registry script to restore the preferences after one of these events.

The settings we need are:

1.) Documents / Allow documents to hide the menu bar, toolbars, and window controls (DISABLE)

2.) General / Touch Mode (NEVER)

3.) Security (Enhanced) / Enable Protected Mode (DISABLE)

4.) Security (Enhanced) / Enable Enhanced Security (DISABLE)

I've found several guides with Adobe Registry Settings, but not for the Preferences.
