Some apps utilize the ImeMode property to control the IME (Input Method Editor) mode for individual text entry fields to increase typing efficiency. Some IMEs in Windows 10, version 2004 (the May 2020 Update) might have issues using the ImeMode property with certain apps. For example, the input mode will not switch automatically to Kanji or Hiragana.
To work around this issue in the short term, either manually switch the input mode when typing, or by following the steps below to enable compatibility mode:
- Select Start, type Settings and select it or press enter.
- Type IME settings into the search box within Settings and select the IME settings that are appropriate to your language, for example Japanese IME Settings.
- Select General.
- Turn on Use previous version of Microsoft IME.
Note We do not recommend using the compatibility setting for the long term, but rather as a temporary workaround for users who are impacted by this issue.
Microsoft is working on a resolution and will provide an update in an upcoming release.
