Window Screen Opening And Closing At Startup Instantly

I have two computers that have win 7 x64 pro/ult. Recently, both computers, after typing in my poassword for login to windows, I get the desktop, icons, the hardware meter gadgets, then a windows pops up, near the top left corner, about a 1/6 of the screen size, and it immediately closes. It isn't there long enough for me to read anything in it, or even see if there is anything in it. Under start-up folder in the start menu, both computers do have logitech registration.

I click it, fill it out, and re start the computer. Still happens, and the start up folder still has logitech's product registration there. I complete it, restart the computer, and the window still shows up, then closes. Damn near instantly. Under start-up, the logitech thing is gone, so it is blank. But it still happens. Installing the webcam and using it for Logitech Vid, is the only thing I have changed recently on both computers. Also, windows 7 did have an update. I have no idea what to look for in regedit.
