Win7 in the modification of the registry custom boot login interface background picture graphic tutorial

I think many people like to personalize their own computer, often will customize the background image of the login interface, compared with other people's computer It will be different. To modify the background image of the login interface, the easiest way is to use some optimization software to modify the Rubik's Cube. If you do not install the software, you can modify the registry to modify the background image of the login interface.

Before making changes to the registry, you need to do some preparatory work and find a wallpaper. The wallpaper requirements are:

1. The picture must be named "backgroundDefault.jpg”

2, the picture must be less than 250kb

If the picture does not meet the above requirements, then the background image will not take effect, and many people who modify the registry to change the background are here.

Next press “Win+R”output“regedit”Open the Registry Editor and expand in the left window, HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Authentication\\LogonUI\\Background, Find the subkey of “OEMBackground”, right click to modify its key value and change 0 to 1. The purpose is to enable the user-defined background image function. Many brand machines boot and login screens with the logo of the merchant logo are changed like this.

Then put the background image you want to ask the login interface to the path specified by the system. Open the C drive and find the Windows\\System32\\oobe\\ folder. Create a new folder in oobe and name it "info", then create a new folder in the info folder and name it "backgrounds", and finally put our prepared backgroundDefault.jpg into the backgrounds folder.

Press “Win+L” to see our results, if not, log out or restart the computer. The next time you want to change the background image of the login interface, you can change the backgroundDefault.jpg in the backgrounds to take effect immediately.

The problem that arises is that many desktop wallpapers are now M-sized, and there are very few wallpapers smaller than 250kb. My own solution is to use the Fireworks Export Wizard to compress the image size. You can also try Use other software to compress the size of the wallpaper.
