This one surprised me, I confess.
By default, when you have two monitors installed, the taskbar is duplicated on both monitors. That's kind of ... wasteful, wouldn't you say?
So right-click either taskbar, click Properties, and look at the options under the Multiple displays heading. Clear the Show taskbar on all displays checkbox if you want only one taskbar on the main display. My preference, though, is to show all taskbar buttons on the main display and on the secondary display show only buttons for programs actually on that display.
If you use multiple monitors, try this. You'll like it.
Speaking of multiple monitors...
Windows 8 finally overcomes one of the most frustrating multi-mon limitations in Windows 7. You can now display a different desktop background on each monitor.
To make it happen, right-click the desktop, choose Personalize, and then click Desktop background to open this dialog box.
Right-click any image to see the very well hidden shortcut menu shown here. Pick one image for Monitor 1, another for Monitor 2, and you're done.
Bonus: If you choose multiple images and set them as a slideshow, you can change the pacing for each monitor so that it's constantly mixing images.
Sometimes, you just want a fresh start. With Windows, a clean install offers instant relief from the strange ailments that can befall a system where you've been messing around with poorly written desktop applications.
Windows 8 offers two quick and easy alternatives to the traditional (and tedious) full install. The first is a Reset, which restores your system to its like-new condition, wiping out all your data files and settings in the process.
The second option, Refresh your PC, is much kinder and gentler. It restores your system like a clean install, but doesn't tamper with your data, your settings, or your Metro style apps. You need to reinstall any programs you installed from downloads or disks, a process made easier by the list that appears on your desktop.
To make the process even easier, you can create a custom refresh image using the command line tool I document in Save a custom refresh point .
