If you are using Windows 10 and just know you are typing in the right password, and your password contains a # or a £ sign for example, then this article should help you out.

You will need to know what the American keyboard looks like. Here is a picture:

So if you have a # in your password, you will need to press SHIFT+3 at the logon screen.

How can I fix this?

To resolve this you will first need to be able to log in – hopefully the above will help. Then:

Open Control Panel
(View by: Small icons)
Click on Language
Click Advanced settings (left hand side)
Now click the Apply language settings to welcome screen… option as seen below:

Control Panel srcset= Language > Advanced settings” width=”532″ height=”162″>

On the next screen, click the Copy settings… button
Tick the bottom two boxes and press OK

That should do it for next time you reboot your computer.
While you are at it, why not go download the English (United Kingdom) language pack?
