Hello there ChristineF42,
My name is Jin and I am an Independent Advisor. The Microsoft text input application is integrated with Windows 10, disabling the app may lead to some applications to not work properly.
If you encounter as such, you can run the automated troubleshooter. Please refer to the article below:
