Run a program or script as another user, there is sudo -u in Unix-like, but there is no sudo -u command in Windows, the nearest equivalent is runas command.

But can't pipe a password into runas, because it requests the password from the terminal, not from stdin.

So, I have to reimplement ProcessImpl.java, ProcessEnvironment.java and ProcessBuilder.java for Windows.

First, for Windows, I will reimplement it by JNA:

ProcessBuilder.java: copy and rewrite it

ProcessEnvironment.java: rewrrite it by JNA

private static native String environmentBlock();

ProcessImpl.java: rewrrite it by JNA

private static native int getStillActive();
private static native int getExitCodeProcess(long handle);
private static native void waitForInterruptibly(long handle);
private static native void waitForTimeoutInterruptibly(long handle, long timeout);
private static native void terminateProcess(long handle);
private static native boolean isProcessAlive(long handle);
private static synchronized native long create(String cmdstr, String envblock, String dir, long[] stdHandles, boolean redirectErrorStream)
private static native long openForAtomicAppend(String path) throws IOException;
private static native boolean closeHandle(long handle);

Finally, I will create new file in ds, like ProcessBuilderForWin32.java, ProcessEnvironmentForWin32.java, ProcessImplForWin32.java

So, how about it?
