Hi CLARAMA2,
Thank you for posting your query in the Microsoft Community Forums.
You have an issue with the keyboard typing in upper case. It can be difficult when something that is important to you does not work as expected. It is pretty simple and we are here to help you fix the issue. We will work as a team and get this sorted out.
Please answer these questions-
1) Does this issue occur while typing on all the applications on the computer?
2) Have you made any other changes on the computer?
I would like more information regarding the issue.
Method 1–
I would have you refer the steps to undo the changes-
a) Identify the “Caps lock” on the keyboard and check if the second light is lit from the list of three lights on top right corner of the keyboard.
b) If the light is lit, then it means that CAPS LOCK is “on”.
c) You need to press the CAPS LOCK once again and make sure that the light disappears as well.
d) Now, try and type. Check if the issue persists.
Method 2-
If the issue is recent, then you can also perform a System Restore to undo the changes made on the computer.
Refer the articles-

Note: Performing a System Restore will undo any changes made on your computer earlier. You may also lose unsaved information as well. Proceed at your own risk.
