Has Microsoft goofed up Windows Update again?

I'm getting reports that Microsoft has been goofing about with Windows Update again and changing settings without user permission:

Woke up this morning to a Windows log in screen? Swear you set that option "Download updates but let me choose whether to install them"? We did too.

In what appears to be a major glitch at Microsoft, Windows users are trickling in from across the globe reporting that their machines downloaded and installed updates they did not consent to. Rubbing salt in the wound, machines were also automatically and forcefully rebooted at the default 3am time frame.

We have requested comment from someone on the Windows Update team as this incident raises serious questions -- Why does Windows have the capability to override a user's choice? What are the legal ramifications for installing software on a machine without consent? Is the user still bound by the EULA they never read?

I can't say that I've noticed this but I'll look into it.  If anyone has experienced this I'd like to hear from you.  It seems that only Vista is affected by this issue.  If this is true, I'm interested how this fits in with Microsoft's promise to be more transparent and open with updates.

Thoughts?  What's up with the Windows Update team?
