How to fix games that won't run full screen mode on windows 7/8/8.1

Recently I upgrade my new laptop from windows 7 ultimate to windows 8/8.1. After installing some games like Need for Speed Most Wanted I found that the game won’t run in full screen mode I was disappointed and never like movies showing at the middle of the screen much less my games so I got it fixed this is how I did it.

•         Press windows + R on the keyboard or go to “Start Menu -> Accessories -> Run” to open “Run”.
•    Type “regedit”. Registry Editor will open

• Go to “HKEY_LOCAL_MACHINE -> SYSTEM -> ControlSet001 -> Control ->GraphicsDrivers -> Configuration -> LEN40350_00_07D9........... -> 00 -> 00

 Note: The above directory named “LEN40350_00_07D9 .........” may have different name on your system according to the monitor and video drivers you are using. The configuration directory can contain more than one sub directories like in the above image have three sub directories MSBDD_LEN40350_00_07D9_82......  then do set scaling value for all of them.

• On the right side area you will see a key named “Scaling” show in the image above 
• Double click on it and change the “Value Data” field to 3. Base will be “Hexadecimal

 The “Value data” key means different for different values:

             2 > Center Image

             3 > Scale Full Screen

             4 > Maintain Aspect Ratio

• Click OK and close Registry Editor.

                                                             Your problem should be solved.
