Re:Conditional Windows Software Update
anything could be scripted... that said, what exactly is the end goal?
I'm hoping that some of the built-in features of CM, like Service Windows, would be a better fit for whatever it is your final goal happens to be.
To me, you wanting to "do something" based on a text file means that some human is putting that text file there. Seems high-maintenance to me. I would hope that with a little planning, you could instead plan on what boxes should be in what Service Windows and allow (for example) the boxes on the East Coast can be patched on Saturday, and the boxes on the West Coast can be patched on Sunday.
