I want to disable internet for Windows 7 which is running in Parallels. Reason: I'm tired of a million apps asking me to update and slowing everything down/checking for updates. Is there a way to still keep Parallels online though so I don't miss their updates? And obviously I don't want to disable internet to the Mac OS. Otherwise, I'd simply turn off the modem. Let's see this wonderful community keep its track record up with me.
