HI, I am Dave, I will help you with this.
This usually happens when the keyboard language set in Windows does not match the language of your physical keyboard.
1
If the @ symbol on your keyboard is above the 2, you have a US English Keyboard
If the " symbol on your keyboard is above the 2, you have a UK English Keyboard
Check in the Settings App - Time and Language - Language to see if your keyboard language is set correctly.

If that is not what is above the number 2 on your keyboard, please provide a photo of your keyboard, so I can work out the correctly language of that layout.
