I pretty much grasp most of the guts of the Windows 7 operating system... configuring it and optomizing it (group policy editor, etc). One of the biggest thing that has always thrown me off (ever since Vista was created) were premissions, credentials, users, and groups. Does anybody know of a good book or really good online resource that explains it in depth, but easy to understand? I don't know why I have such a problem with it... but it's so confusing to me, when hardly anything else is. Thanks guys.. any help is always appreciated.
