Answer 1

Here is how to disable ad hoc networks on Vista, It should work on W7 as well

Windows Vista won’t automatically create ad hoc wireless connections with other computers, but for greater security you may want to disable ad-hoc wireless connections entirely. You can do this by running the following Netsh command at an elevated command prompt:

netsh wlan add filter permission=denyall networktype=adhoc

To re-enable ad hoc wireless connections, run this command:

netsh wlan del filter permission=denyall networktype=adhoc

If you go to Network and Sharing Center then select from the left hand "Manage Wireless Networks", you should see every wireless network your computer is set to automatically connect to.

If there are no Ad-Hoc Networks listed, your machine will not connect to one automatically.

As long as you do not create or join an Ad-Hoc network, your machine will never automatically connect to one (Unless someone Spoofs one with the same name as a network you use etc, but that is always the risk of using wireless - and it is highly unlikely).

There is a more complicated way of actually disabling it - If you have access to group policy editor and the Wireless templates, you can set it to only connect to "Access point (infrastructure) network only." If you want a full guide for this, let me know and I will write one.
