Internet Explorer 7 Beta Preview
Posted on Wednesday 1 February 2006

Download it here:
http://www.microsoft.com/windows/IE/ie7/ie7betaredirect.mspx

To install it alongside your current ie6 :

Once the IE7 installer file is downloaded, extract the files via WinRAR, or any other archiving software that can extract an exe file.

1. Open the folder where you extracted the IE7 files, and delete the file SHLWAPI.DLL and the folder Update.
2. Open a text editor, like Notepad, and save a blank file as ‘IEXPLORE.exe.local’ to the IE7 folder.
3. Click iexplore.exe from the IE7 folder

However, it looks like you can’t run the browser as a limited user on a PC, even if its not under a protected folder.
