6to4 Adapter Removal
Some users have been reporting issues with startup times that are related to there being a huge number of network adapters in their systems with names like
net232 (6TO4 Adapter) net100 (Microsoft 6to4 Adapter #85)
Things can be improved by deleting these: see

You need to first go to http://support.microsoft.com/kb/311272 and click on the link to download Devcon.exe, click on it to run it and it will open a 'unzip to folder' dialog. Type in something like C:\Temp\devcon - this will extract files into
C:\Temp\devcon\i386 C:\Temp\devcon\ia64
If you have a 32 bit version of Windows the folder you're interested in is
C:\Temp\devcon\i386
If 64 bit then
C:\Temp\devcon\ia64
Now download http://www.ryanvictory.com/downloads/6to4remover.zip
and unzip this file into
C:\Temp\devcon\i386 or \ia64 as appropriate
Look in that folder, you should now have two files in there:
6to4remover.bat devcon.exe
Double click the 6to4remover.bat file to run it.
