This week’s tip comes after another successful “Tech.Days Online” session in late April, delivered by a host of specialists covering a range of developer and IT Pro topics. The Tech.Days Online programme of events is interesting in that it’s delivered “live” to thousands of virtual attendees: in other words, you could visit the Chicago auditorium and see the whole thing being presented to an empty room, except for the camera and audio crew and perhaps a few interested supporters.
Andrew Fryer suggested this update of an old feature of the somewhat-maligned Windows Vista. Pressing WindowsKey+X on a Veesta machine would display the Mobility Center, a collection of tools that are relevant to laptop use. In Windows 8, the Win+X combination has grown somewhat, and throws up 
a list of potentially useful utilities and quick access to the more commonly used (by technical types, anyway) aspects of the Control Panel. On a laptop, Mobility Center also features here.
If you like it particularly and a few more clicks is too much to ask, you could even start the Mobility Center then pin it to Taskbar for future one-hit execution. 
The Presentation Settings applet in Mobility Center will allow you to configure how your machine looks and feels whilst you’re presenting – maybe change the background image of your desktop from a leering photo of your dog/child/spouse, to something a little more corporate and dry. Or don’t let the screen go blank, even if you’re running on battery… To set the options up, click on the projector icon within the Mobility Center. 
It doesn’t set your Lync status to tell people you’re presenting, and it won’t configure PowerPoint to send things to the right screen, though… more on that in a future tip.
