If you’re unfamiliar, Microsoft has a troubleshooting feature called “Guided Help” which is supposed to be able to automatically fix common problems for you. Great idea, if it works. I’ve never used it, but this Microsoft Knowledge Base article does not instill in me confidence in this feature.
From the article:
Guided Help is available to help recover a corrupted registry that prevents Windows XP from starting. Guided Help can automatically perform the steps for you.
And a couple of paragraphs down:
Requirements to install and to use this Guided Help
You must be logged on to Windows by using a computer administrator account to install and to use this Guided Help.
I have to go lie down, because my head hurts now.
