Activation/Wireless Service problems/Windows Update not working/smss.exe stops

Hello,

I've been able to get logged in (after disabling UAP to authenticate Vista -
do I need to enable this now?). I find everytime I log in that the Windows
Wireless Service is not running. So I go to manage network connections,
right-click and select diagnose on the connection set-up for my wireless
router (which I had to set-up manually). Once I have started the Wireless
Service, when I select to activate Vista it tells me that a change has
occurred in my license and I need to restart. This happens every time. If
I try and activate Vista before I start up the Wireless Service then it
tries to connect without an error, but then, of course, I have to start it
up and then get the license error (so basically stuck in a loop). I also
receive a license error: 0XC004D401.

I cannot update Windows Update either. RealPlayer and ZoneAlarm don't run
or work and I canot update Windows Defender.

And I eventually receive an error telling me smss.exe has stopped and been
closed.

Any ideas?
