<human>: Can you summarize the given text in a few sentences?

I recently installed windows 8 on my computer and looked around all the new features; I logged into facebook using the facebook app, installed the e-mail app, and just generally messed around with the new OS. I decided I didn't like the full screen apps so I decided not to touch them anymore and I forgot about them.

Anyways, today I had to demo to some managers a tool that I have been working on for quite a while so that it could get submitted to higher ups for review. I'm demoing my tool by using a projector so that everyone can see. Everything was going well, managers were excited about tool features and were asking questions when suddenly a friend starts messaging me on facebook about how he is really mad about something that happened with his gf and starts using some select words... (n,c,f,a,mf,p, all of those nice words were used in describing certain people) and worst of all windows 8 posts all of these messages as a message overlay so now everyone is reading these beautiful messages. They stop for a second so I continue on with the presentation while ignoring the messages... and then they start again. One of the managers just walks out and then I pull the plug and apologize and quickly search how to turn off message overlay so I can finish the presentation.
<bot>: Windows 8 overlays messages during an important meeting presentation while some friend is messaging a bunch of non-work-friendly words.
