Just print this to a file and keep it around. I did.
There are times when the command line is faster, cleaner and easier, if only you have practiced enough that it is not really alien to you. That's all you need to do in preparation. When the time comes, you simply rip out your how-to literature and have at it.
I used the command line this morning to remove a rootkit from a Vista machine. It was easy, fast and saved me having to download a removal tool and use that. The AV program would not do it alone and so I stepped in and did it by hand. The machine is now clean and I saved a bundle of time.
You can, too.
