Well, i was stack with a problem for last 2 hrs. Now finally i got the solution. The problem was when i type M on my laptop it shows 0, then K=2, L=3, O=6,P=7. So i was little mad because when i start my laptop i can put my password with same key but that time it was ok. Another problem that i am using windows 8 and there are lots of keyboard option. So i thought it could be for this reason. Working on that for hours but no result. Finalli i got some solution.
(This is for Windows xp and 7)
Go to the Control Panel
Click on “Regional and Language Services”
Click on the “Languages” tab
Click on “Details”
Click on “Key Settings”
Select “Switch Between Input Languages” and click “Change Key Sequence”
Make sure all the boxes are unchecked.
Do the same thing with “Switch to… (Keyboard type)”
Or if u are using external keyboard with your Laptop then simply click on Fn+Num. Hope guys it will help you.
