My torn data pages - Vista UAC and SQL Server Management Studio

Okay, you are an administrator, for you just successfully installed the SQL Server on your Vista box. Now you want to start SSMS. 

If you just click this, you're likely not able to logon with Windows Authentication although you are member of BUILTIN\administrators (how else did you install?)!!! This is User Account Control (UAC) trying to nag you, but there are five ways to be relieved of this behavior:

1. Log on as sa in Mixed Authentication mode. Not recommended, besides you either had to have this configured during install, or have to do it now (go to point 2 to get started).
2. Right-click SQL Server Management Studio and "Run as administrator" (if you don't want to do this every time you start SSMS, go to point 3).
3. Add your user account, or an appropriate group (other than BUILTIN\administrators) where you're a member as a login with the sysadmin server role.
4. If your fed up with UAC altogether, visit the How-To Geek
5. Install SP2 and use the SQL Provisioning tool after the Service Pack is applied.
