When a Windows 10 session is launched from Workspace app for Linux and Workspace app for iOS , we cannot type anything inside a session

1. Change the Windows language to English (US)
Settings -> Time & Language -> Region & Language -> Add language -> English (US)

2. If language is already added , check for the keyboard :
Settings -> Time & Language -> Region & Language -> English (US) -> Options -> Keyboards -> Add US (QWERTY)

3.Check the registry entry and make sure English US keyboard is added :
Computer\HKEY_USERS\.DEFAULT\Keyboard Layout\Preload



00000409 is for English US keyboard
00004009 is for English India keyboard

4. Make sure there are no substitutes entry in the registry :
Computer\HKEY_USERS\.DEFAULT\Keyboard Layout\Substitutes

5. Logout from the current session and login again.
