Wt.exe is the executable name of Windows Terminal. By default. The wt.exe is installed under C:\\User\\username\\AppData\\Local\\Microsoft\\WindowsApps. Normally, wt.exe is automatically installed for all users when you are installing Windows 11. If needed, you can access and check the wt.exe file in this location in case it is missing from Windows 11 and leads to this Windows Terminal not working issue.
