Welcome to PPV

Vista Service Pack 1, still in beta, has been released to selected beta testers. If you can't wait for the final Service Pack (I don't care what's your reason), here's a tip to get it. This is from ghacks.net, and several sites reports that this simple registry tweak is fool proof at the the time of writing this post - unless MS finds a way to fix it.

Downloading Windows Vista Service Pack 1 from Windows Updates:

• Download Windows Vista Service Pack and unpack it to your system.
  
• Run SP1Beta_Hack.cmd with administrator privileges and Windows Updates afterwards. It should show KB935509 which you should download and restart afterwards.
  
• Run Windows Updates again, it should display KB937287. Download and restart your PC afterwards.
  
• Run Windows Updates for a third time. Download the now appearing KB938371, restart your computer.
  
• Finally, visit Windows Updates again and you should see the Service Pack 1 Beta for Microsoft Windows Vista available for download.
  

Removing the Evaluation Copy message:

• This is fairly easy to accomplish. Run watermark_fix.reg first
  
• Rename user32.dll.mui to user32.dll.mui.old in C:\Windows\System32\en-US\
  
• copy user32.dll.mui from the archive to that location
  
• Reboot Windows Vista
