If you are interested, Internet Explorer 10 is now available for Windows 7. The redesigned browser, Internet Explorer 10, made its debut last month when Microsoft released Windows 8, which makes dramatic changes to an operating system that has been powering PCs for decades.
Internet Explorer 10 initially is being introduced Tuesday to Windows 7 users in a "preview," or test, mode. The new browser isn't compatible with XP, Vista and any other older Windows version.
Although Microsoft is staking its future on Windows 8, far more PCs rely on Windows 7. Microsoft Corp. says more than 670 million licenses for Windows 7 have been sold since its release in 2009. Windows 8 is unlikely to approach that level of usage until at least 2014, based on analyst forecasts.
Desktops, laptops and tablet computers running on Windows 8 are sold with Internet Explorer 10 already installed. Those with older Windows versions will have to download and install the new browser separately.
Although Internet Explorer 10 is supposed to process Web pages more quickly and smoothly than its predecessors, it may have limited appeal to Windows 7 users.
That's because Microsoft primarily designed Internet Explorer 10 for tablet computers and other devices, including a new breed of PCs that have touch-screen displays. Relatively few Windows 7 PCs can be controlled with fingers on a display screen.
