It seems like the MelindaGates hack allows users to download a VMware image of a KMS server which activates Windows Vista Business/Enterprise edition, its creators claim.
There are no Corporate keys anymore for activating Windows so companies can host a local activation server which does not talk to m$ (KMS).
Another possibility can be found on this website. They have setup a KMS server where you can theoretically activate your copy too. So there is no need to download the VMware image 
Are you also fed up with switching the network settings and clicking like crazy? I found a way to automate it.
You need: standard windows tools
Go to command line and create a directory. In my case it is c:\nw
next you have to dump the actual settings to a file. Do it with “netsh -c interface dump>conf1.txt”
Now create a *.bat file and put in:
@ECHO OFF
ECHO loading network settings
netsh -f c:\nw\conf1.txt
For changing settings you can create more conf.txt files and more *.bat
Elecom presents some awesome devices for LANs.
