Programmatic Windiows Explorer stop and restart

Hi,

My question is how to properly restart Windows Explorer from a program I wrote.

Details:
I wrote a program that run as Desktop with Windows 8.
After the program is started, it automatically Quit Explorer.exe (finding the PID and quitting/close)
and all is fine. Before my program will be quitted by the user, I want to restart the
Explorer.exe. It works but I get error message when trying to use the restarted
Explorer with APP in the Metro/modern UI.

From what I understand, reason is that my program is running as administrator and
when re-launching Explorer.exe also Explorer.exe is runned as administrator and this
do not allow Metro APPs to be used.

I observed that when restarting Explorer.exe using my program it get the BUILTIN/ADMINISTRATORS
as OWNER, while if restarting within the task manager it is as DENY.

Is there any way to tell Explorer.exe to run as BUILTIN/ADMINISTRATORS DENY and overcome the issue?

Thanks for the attention and hints.

I don't know of a simple way of doing this.
While are you killing the explorer.exe process at all?
Normally it would be highly inappropriate for a program to do this.
