Found it! In "MyComputer//ControlPanel/Performance and Maintenance/See Basic Information (System Properties)/Automatic Updates"  I found that windows has its automatic update download time set to 3:00am.    I normally turn the computer off when I'm  not using it, so a bunch of updates must have accumulated and then kicked off when I got past the 3:00am point. (When I'm using Poser, I'm USING Poser).  

I'm sorry for the wild goose chase. But as long as my system specs are out there, can anyone see room for upgrading?
