1. First, we need to download a picture of their own, they feel good-looking, need to set up for the welcome interface of the picture, but the size of the picture is standard, must be less than 256KB, if the downloaded picture is too large, we can use the corresponding tool to modify.
2. After that, we enter into the c:windowssystem32oobeinfobackgrounds according to the path, then save the picture we downloaded, if we do not have this path to create this path in turn.
3. When finished, we also press the Win+r shortcut key on the Win7 flagship computer keyboard to open the computer's running window, then enter regedit and click Enter, in the Open Registry Editor window, we navigate to hkey_local_machine/software/ Microsoft/windows/currentversion/authentication/logoui/backgroud, click Background, then right-click on the right margin and select "New" "String value", and name the new value Oembackground.
4. When finished, we double-click the new value, change the value data to 1, then click OK to save.
When we're done, we'll sign out of our Win7 flagship computer and we'll see that the Welcome screen becomes our own downloaded image.
