An ugly idea:
Use windows task scheduler to start a new browser displaying that webpage.
Most browsers allow you to specify the startpage like this
"C:\Program Files (x86)\Internet Explorer\iexplore.exe" http://superuser.com/
T+0: Start webpage 1
T+10min Kill all browser processes, start a new browser with webpage 2
T+12min Kill all browser processes, start a new browser with webpage 3
etc etc
To kill the browser you could use taskkill /f /im iexplore.exe*
.
Personally I find this an ugly way to do it, but it seems one way to accomplish your task.
A much neater way would be something like creating a single webpage, display that. Use javascript to periodically refresh the webpage (where each refresh loads from a different page). Much cleaner, but the person maintaining that will need to understand how webpages and or javascript works.
