Crank up your favorite registry editor and make the following change:

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
"MaxConnectionsPer1_0Server"=dword:00000019
"MaxConnectionsPerServer"=dword:00000019

Make shortcuts to your favorite sites:
Create a normal Windows shortcut, in the "Type the location of the item:" text box enter: "c:\program files\internet explorer\iexplore.exe" www.google.com

Hold the shift key while clicking a hyperlink to open the page in a new window

Automatically delete temporary internet files when exiting internet explorer: Click Tools, Internet Options, Advanced tab - scroll to the security section and select the: Empty Temporary Internet files folder when browser is closed check box.

Make Google Internet Explorer's default search engine:
Google has a link for a registry hack: http://www.google.com/google.reg
The changes are:
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main]
"Use Search Asst"="no"
"Search Page"="http://www.google.com"
"Search Bar"="http://www.google.com/ie"
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\SearchURL]
""="http://www.google.com/keyword/%s"
"provider"="gogl"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Search]
"SearchAssistant"="http://www.google.com/ie"

To download the full version of Internet Explorer, download the iesetup.exe file from MS. Once you have that file, run the following command:
ie6setup.exe /c:\"ie6wzd.exe /d /s:\"\"#E\"
It will ask you which folder to save the files to and which OSs you want to download for.
