I know this isn't really Cemetech's niche here, but I thought since almost 105% of you are tech savvy, I could find an answer here.

Is there any program that I can save an 'instance' of something with?

I live-stream video games in my spare time over on twitch.tv, and I use two alert systems, one for new followers, and one for donations. These alerts are simply in a browser window (one for each), that have to be set to a certain size every time. So rather than go through the hassle of setting the two window sizes every time, it would be nice if there was a way I can say, "Save these two windows, and let's open them up exactly like this next time."

Now this is pushing it, but it would also be cool if I executed this program and it loaded my streaming software and these two browser windows at once. That's hoping for a lot, but maybe you guys at least know of something that could help me out?

Thanks again Cemetech

You could probably create a script on a simple html page that opens the windows with the correct layout.
For opening the browser windows and also opening your streaming software, a simple vbscript might also be what you need instead.
Another option would be to use the script on the html page to open the windows perfectly and the VBScript to kick off that html page and to start your streaming software.
