After a user logs in to a VM, the English input mode is always set as the default input mode. After the English input mode is deleted and the user logs in to the VM again, this problem still exists.
1. Log in to all WI servers, back up the default.ica files in the C:\inetpub\wwwroot\VDesktop\conf\ and C:\inetpub\wwwroot\VDesktopPNA\conf\ directories. Add KeyboardLayout=(Server Default) under the SessionReliabilityTTL=15 line.
2. Change the default input mode to a non-English input mode on the VM and logs in to the VM again.
The default input mode can be configured in the configuration file of WI.
