I’ve been in an automating mood lately – old school, batch script style.

Here’s another one I cooked up to relieve you of tedious steps needed to turn off all advanced networking features in
Windows 2008/Vista/7.

As a bonus, I added before and after logging for fun.

As a side note, I was not able to cook up a way to dynamically enumerate network connections and uncheck the IPv6 protocol for you…this is still done manually. Perhaps with more time, I could fix this.

Regardless, this little batch file has saved me a bit of time already.

Again, use all but the asterisks for the batch file…
