Windows system settings

Small utility that sets Windows settings via the back-end used by the Windows 10 setting app.

⚠️ ☢️ ☣️ 🔞 🚭

This tool has the potential to make most Windows settings easily configurable. Howewer, the Windows Settings back-end is undocumented. Under-handed techniques are used, and some settings will crash. Different OS releases may have different settings.

The interesting code is in the SettingsHelper.

Usage

Reads a JSON array of payloads from stdin:

SettingsHelper < payload.json

List all possible settings for the current system:

SettingsHelper -list

Payload JSON

The payload sent to the application's standard input looks like this:

[
    {
        "settingID": "SystemSettings_Accessibility_Magnifier_IsEnabled",
        "method": "SetValue",
        "parameters": [ true ]
    }
]

• settingID: The setting ID. See SettingsHelper -list
• method: The method of to invoke.
• parameters: Parameters to pass (optional).

There can be several items, allowing more than one setting to be applied.

Example: Turn "night mode" on:

[
    {
        "settingID": "SystemSettings_Display_BlueLight_ManualToggleQuickAction",
        "method": "GetValue"
    }
]
