Change your WIN 7 startup Background

Presently you people will be able to change only and only desktop background , but today I am going to tell you How to Change Start Up Background of Win 7.

Make sure that you follow each and every steps accurately, other wise it will be difficult to correct the problem and you need to restore your system

Follow the steps for setup :

Step to Setup Registry Entry :

• Click on start, in search box type "run" and press enter.
• In run commend type "regedit". and press Enter.

• Then a window will popup, click yes to it.
• Click on drop down menu of "computer" which is at top left of the opened box, select "HKEY_LOCAL_MACHINE", then select "SOFTWARE" , then go to "Microsoft" , then go to "Windows", then "CurrentVersion" then "Authentication" then go to "LogonUI" at last go to "Background".
• After that go to "OEMBackground" on the right side of space.
• Right click on it and select "Modify", select "Value data as 1" and "Base as Hexadecimal".
• Click "OK" and close the window.

Steps to Change the Background :

• Rename the Picture you want to set as the Startup Background as "background"
• Copy the file and paste it at "C:\Windows\SysWOW64\oobe"
• Go to following location "C:\Windows\System32\oobe\INFO\backgrounds", Paste the same file here also. Rename this file as "backgroundDefault", as a file with same name will be already existing, first change its name by adding 1 at last to it. 
• Then close the Window.
• Either time you lock the screen or restart the system , your start up background will change with your desired pic.

Steps with Pictures :

Enjoy the Day ..!!!!!!!!

Basic Interfacing GLCD with ATmega16

Following is the program to Generate the basic verticle line on the glcd at and 0th Column.
Connection is shown in the Image. PORTC is reserved for the Control Port and PORTB for data Port.
Here we had not used any Library for this purpose.
