Driver Windows 8 for All Laptop (Acer, Apple, Asus, Dell, e-Machine, Fujitsu, Gateway, HP, Lenovo, Panasonic, Samsung, Sony, Toshiba, Visio, Microsoft)

Fancy yourself an early adopter, but don't want to shell out the money to buy one of the many new Windows 8 systems offered by Microsoft and other manufacturers? What about those who bought a new PC recently, and find themselves stuck with Windows 7? Well, you're in luck, because Microsoft, in an effort to boost Windows 8 adoption, is offering to upgrade eligible systems on the cheap. For $14.99—15 bucks!—anyone who purchased a qualified Windows 7 laptop after June 2 of this year can purchase a download of Windows 8 Pro. And for those who don't meet those requirements, the full operating system can still be purchased for $39.99 (via download) or $69.99 (on disc).

But not all laptops will be able to make the jump to Windows 8. According to Microsoft, the minimum hardware requirements for running Windows 8 include a processor with a clock speed of 1GHz or more; at least 2GB of RAM for 64-bit systems (or 1GB for 32-bit), 20GB of hard drive space (16GB for 32-bit), and DirectX 9-capable graphics. Most—but not all—PCs running Windows 7 will meet these requirements, but it should be noted that if you purchased Windows 7 Starter Edition, you'll be paying full price.

You should also know that many features integral to getting the full Windows 8 experience require further hardware capabilities. The touch-based navigation that Windows 8 is built around requires a touch screen, though touch-enabled peripherals can make up some of the difference. Purchasing and downloading apps for the Windows Store—which Microsoft expects will be your primary source of apps and software—requires an active Internet connection. And while the operating system will work at resolutions as low as 1,024-by-768, you'll need to bump that up to at least 1366-by-768 in order to use apps side-by-side.

Beyond the basic hardware requirements, you'll also need device drivers to get all of your hardware playing nicely with the new operating system. While most manufacturers are offering driver support for PCs sold over the last year, the cutoff date varies, so check the details for your specific brand below. And if you don't see your brand below, check back over the next few weeks, as we will be updating this story as more information becomes available.
