Windows 8 is coming.
Although you may not be jumping for joy at this fact, I'll wager you're at least a little curious. Could the new OS make your computing life any better? Is the new interface a boon, or more of a boondoggle?
Fortunately, you don't have to sacrifice your current PC to find out -- nor do you have to buy a new one. You can install theWindows 8 Release Preview alongside Windows 7 and take it for a full test-drive. It's simply a matter of setting up a dual-boot configuration.
Before you go one step further, make sure you have a complete backup of your hard drive, just in case things go wrong. This is a pretty safe operation, but you never know.
