What's the longest you've had to wait for a Windows update to complete?

My brand new laptop wanted to install five updates tonight, so I let it. It’s been stuck on update number one for thirty minutes now. I don’t know how long to wait before feeling nervous–nor what to do should things reach that point…

It’s not a super fast machine (a cheap $400 laptop) but still… A8 processor so not exactly a Celeron either…

How long have you had to wait for updates to complete?

(It’s a Windows 8 machine btw.)

I don’t know whether it would a good idea or bad idea to just let it do its thing overnight. But I may not have another option other than switching the thing off mid-update, which sounds foolish…

Do an alt-tab just to make sure there isn’t a dialog box hidden that’s waiting for your input.
