My name is***** am sorry to hear that you are having this issue. Give me a moment to review your issue please.
This sounds like the keyboard layout may have gotten changed. It should be on English U.S.
launch the classic Control Panel, you can do this by pressing the Win + R keyboard combination and selecting Control Panel from the context menu.
switch to the Small icons view.
select the new Language option.
On the right-hand side you will see an options hyperlink, click on it.
From here you will be able to add and remove keyboard layouts.
Let me know if this works.
