Update your IME for Windows 10
If your IME for Windows 7 doesn’t work in Windows 10, than go to your developer’s website to download a new version.
Switch between different IMEs
If you’ve added more than one language to your PC or more than one input method to a language, you can enter text the way you want by switching between IMEs or keyboard layouts.
If you’re using a standard keyboard, press and hold the Windows logo key Windows logo key and then press Spacebar repeatedly to switch between input methods.
If you’re using a tablet or a touch PC, you can switch the input method in the touch keyboard. Tap the touch keyboard button Touch keyboard icon in the bottom-right corner of the touch keyboard, and then tap the input method you want to switch to.
You can also do this from the Settings charm:
Swipe in from the right edge of the screen, then tap Settings.
(If you’re using a mouse, point to the bottom-right corner of the screen, move the mouse pointer up, then click Settings.)
Tap or click the abbreviation for the language that’s selected.
In the list that appears, tap or click the language you want to switch to.
The IME window class is a predefined system global class that defines the appearance and behavior of the standard IME windows. The class is similar to common control classes in that the application creates a window of this class by using the CreateWindowEx function. Like static controls, an IME window does not respond to user input by itself. Instead, it notifies the IME of user input actions and processes control messages sent to it by the IME or applications to carry out a response to the user action.
IME-aware applications sometimes create customized IME windows using the IME window class. Use of window customization allows the application to take advantage of the default processing of the IME window while having control of window positioning.
