My keyboard has gone American..help..

...or so I'm assuming. My " symbol has now been replaced by the @ symbol and I'm just wondering if there is an easy way to get it back in order, some sort of language thing maybe?

go into control panel (or Settings / Windows 8.1/10) and go to "Region & Language Settings" then at the bottom under Preferred Languages, make sure it's "English (United Kingdom" - if not, add it, select it, and remove any "English (United States)"

"@@@

Sorted, cheers Ghozer
