Policy CSP - ADMX_Help
Tip
This CSP contains ADMX-backed policies which require a special SyncML format to enable or disable. You must specify the data type in the SyncML as <Format>chr</Format>. For details, see Understanding ADMX-backed policies.
The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see CDATA Sections.

./Device/Vendor/MSFT/Policy/Config/ADMX_Help/DisableHHDEP
This policy setting allows you to exclude HTML Help Executable from being monitored by software-enforced Data Execution Prevention.
Data Execution Prevention (DEP) is designed to block malicious code that takes advantage of exception-handling mechanisms in Windows by monitoring your programs to make sure that they use system memory safely.
If you enable this policy setting, DEP for HTML Help Executable is turned off. This will allow certain legacy ActiveX controls to function without DEP shutting down HTML Help Executable.
If you disable or don't configure this policy setting, DEP is turned on for HTML Help Executable. This provides an additional security benefit, but HTLM Help stops if DEP detects system memory abnormalities.

This is an ADMX-backed policy and requires SyncML format for configuration. For an example of SyncML format, refer to Enabling a policy.

./Device/Vendor/MSFT/Policy/Config/ADMX_Help/HelpQualifiedRootDir_Comp
This policy setting allows you to restrict certain HTML Help commands to function only in HTML Help (.chm) files within specified folders and their subfolders. Alternatively, you can disable these commands on the entire system. It's strongly recommended that only folders requiring administrative privileges be added to this policy setting.
- If you enable this policy setting, the commands function only for .chm files in the specified folders and their subfolders.
To restrict the commands to one or more folders, enable the policy setting and enter the desired folders in the text box on the Settings tab of the Policy Properties dialog box. Use a semicolon to separate folders. For example, to restrict the commands to only .chm files in the %windir%\help folder and D:\somefolder, add the following string to the edit box: "%windir%\help;D:\somefolder".
Note
An environment variable may be used, (for example, %windir%), as long as it's defined on the system. For example, %programfiles% isn't defined on some early versions of Windows.
The "Shortcut" command is used to add a link to a Help topic, and runs executables that are external to the Help file. The "WinHelp" command is used to add a link to a Help topic, and runs a WinHLP32.exe Help (.hlp) file.
To disallow the "Shortcut" and "WinHelp" commands on the entire local system, enable the policy setting and leave the text box on the Settings tab of the Policy Properties dialog box blank.
- If you disable or don't configure this policy setting, these commands are fully functional for all Help files.
Note
Only folders on the local computer can be specified in this policy setting. You can't use this policy setting to enable the "Shortcut" and "WinHelp" commands for .chm files that are stored on mapped drives or accessed using UNC paths.
For additional options, see the "Restrict these programs from being launched from Help" policy.
