推荐答案

通常这个问题的答案是

reg add "HKCU\Control Panel\Desktop" /v Wallpaper /t REG_SZ /d  "c:\somewhere\something.bmp" /f

以设置在注册表中adecuated条目，随后

to set the adecuated entry in the registry, followed by

RUNDLL32.EXE user32.dll,UpdatePerUserSystemParameters

要通知的变化的系统。

to inform the system of the changes.

BUT ，从Windows Vista这个办法是行不通的。或至少​​不为意。对注册表的更改将应用​​于新的登录。唯一可靠的方法来获得瞬间变壁纸是使用Windows API。

BUT, from windows Vista this approach does not work. Or at least not as intended. The changes to the registry will apply on new logon. The only robust way to get the wallpaper changed instantly is to use the windows api.

有关PowerShell的解决方案，可以在这里找到一个解决办法

如果你有机会获得一个C编译器，这code应该这样做（使用MinGW-GCC测试）

If you have access to a C compiler, this code should do the same (tested with mingw-gcc)

#include <windows.h>
int main(int argc, char **argv)
{
    if (argc < 2) return 1;
    if (! SystemParametersInfo(
            SPI_SETDESKWALLPAPER, 
            0, 
            argv[1],  
            SPIF_UPDATEINIFILE | SPIF_SENDWININICHANGE 
        )) return 2;
    return 0;
}
