Answer 1

使用命令行参数 /c而不是/k来执行命令，然后终止命令shell。

Answer 2

Try /C modifier instead of /K

psi.Arguments = "/env /user:" + "Administrator" + @" %windir%\System32\cmd.exe /C %windir%\System32\reg.exe ADD HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f";

The diffrence between these two is as follows

/C  Carries out the command specified by string and then terminates
/K  Carries out the command specified by string but remains
