Set registry rights and change Component Services with Powershell

Hello,

we must install a lot of SharePoint Server 2010. After the installation, we have to do every time the same thing.

Change the registry owner for the 2 key's: HKEY_CLASSES_ROOT\AppID\{61738644-F196-11D0-9953-00C04FD919C1} and HKEY_CLASSES_ROOT\AppID\{000.....}.

Change the permission for the admin group at this two key's to full.

After i have done this i must go to Win2008 Server -> Administrative Tools -> Component Services -> Computer -> MyComputer -> DCOM Config.

There i have to add users and change permissions at two application class properties -> Security Tab -> Lanch and activation permissions.

I would like to do this with powershell. I hope somebody can give me the instructions for this work.

Thanks Horst
