1. SecurityKISS

On the SecurityKISS download page, you can enter your email address and get 2 PPTP/L2TP VPN accounts, one of which is from USA, and the other one is from UK.

How to change Windows 7 Login Screen

If you want to manually change the login background, you can do so using these instructions. This requires some understand of registry editing, so should only be performed if you understand the consequences. These instructions are for advanced users only, and the above tools should be used if you are unsure.

First, create a key named OEMBackground in HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background if it doesn't already exist and set it's value to 1.

You can now create/replace images in the following folder with your own choice of logon background:

%windir%\system32\oobe\info\backgrounds

These images need to be under 250k in jpg format with the following filenames (sorted by aspect ratio):

backgroundDefault.jpg
background768x1280.jpg (0.6)
background900x1440.jpg (0.625)
background960x1280.jpg (0.75)
background1024x1280.jpg (0.8)
background1280x1024.jpg (1.25)
background1024x768.jpg (1.33-)
background1280x960.jpg (1.33-)
background1600x1200.jpg (1.33-)
background1440x900.jpg (1.6)
background1920x1200.jpg (1.6)
background1280x768.jpg (1.66-)
background1360x768.jpg (1.770833-)

If your resolution isn't listed in one of the above file formats, the backgroundDefault.jpg will be stretched to fit.
