User Configuration\Administrative Templates\Windows Components\IME Description
This policy setting allows you to turn off the ability to use a custom dictionary. If you enable this policy setting, you cannot add, edit, and delete words in the custom dictionary either with GUI tools or APIs. A word registered in the custom dictionary before enabling this policy setting can continue to be used for conversion. If you disable or do not configure this policy setting, the custom dictionary can be used by default. [Clear auto-tuning information] removes self-tuned words from the custom dictionary, even if a group policy setting is turned on. To do this, select Settings > Time & Language > Japanese Options > Microsoft IME Options. If compatibility mode is turned on, select Advanced options > Dictionary/Auto-tuning > [Clear auto-tuning information]. [Clear input history] removes self-tuned words from the custom dictionary, even if a group policy setting is turned on. To do this, select Settings > Time & Language > Japanese Options > Microsoft IME Options > Learning and Dictionary > [Clear input history]. This policy setting is applied to Japanese Microsoft IME. Note: Changes to this setting will not take effect until the user logs off.
