创建虚拟桌面的代码（重启桌面进程）（使用GetThreadDesktop，CreateDesktop，SetThreadDesktop等函数）

在upk 里挖坟得来，有兴趣查查这几个函数...

#include "windows.h"
#pragma comment(lib,"user32.lib")
int main()
{
    STARTUPINFO si;
    PROCESS_INFORMATION pi;
    char DeskName[]="pp";
    HDESK hold = GetThreadDesktop(GetCurrentThreadId());
    HDESK hhdesk = CreateDesktop( DeskName, NULL, NULL, DF_ALLOWOTHERACCOUNTHOOK, GENERIC_ALL, NULL);
    SwitchDesktop( hhdesk);
    SetThreadDesktop( hhdesk);
    ZeroMemory( &si, sizeof(si) );
    si.cb = sizeof(si);
    si.lpDesktop = DeskName;
    ZeroMemory( π, sizeof(pi) );
    CreateProcess( NULL, "explorer", NULL, NULL, FALSE, 0, NULL, NULL, &si, π);
    Sleep(60000);
    SwitchDesktop( hold);
    CloseDesktop( hhdesk);
}
