Are you sure Kaffis? I did some research on the feature before I posted just to confirm what I knew about it, and nothing I ran into stated that it would replace your current configuration, but that it would simply allow you to boot and repair whatever you broke in your main profile.
That's safe mode.
Safe mode boots without loading, well, virtually anything. It doesn't modify anything about your registry or boot-time services or whatever, so you can figure out what went wrong/got corrupted and fix it.
Last Known Good basically is this: whenever you log in normally, Windows essentially copies the registry to a backup. The notion is that if you're able to log in, stuff's working right. When you can't get to the login screen, and/or you crash in the early stages of the login process, you boot into Last Known Good, and it copies from that backup to overwrite the bad **** that's causing crashes/locks.
This means that Last Known Good can get ****, still, as anytime you log in successfully with an error about to explode, it writes that into the backup and you lost your previous Last Known Good which didn't have that. So it's not a fix-all. As a for instance, if something in run or runonce (or something that requires a shutdown to finish so it can do a runonce next time, like maybe an installation of something) is loading a new runonce that's going to crash your computer, you'll be able to Last Known Good all day long, but every time you do, it's going to load the troublemaker back in for the next standard bootup.
