Microsoft has released new figures that indicate nearly half of all Windows 7 installations are running on a 64-bit computing setup. And it could very well be said that Windows 7 is to "blame" for the switch. 54 percent of worldwide systems run the 32-bit version of Windows 7 compared the 46 percent that opts for Windows 7 x64.
Nearly three and a half years after the launch of the OS, Windows Vista users are decidedly 32-bit at a measured percentage of 89 to 11. And, as one might expect, Windows XP users are predominantly running their operating system on a 32-bit system versus 64-bit to a measurement of more than 99 percent to less than one percent, respectively.
The analyst numbers stack up as well. Microsoft cites NPD's Stephen Baker, who says that 77 percent of all retails systems sold in April of 2010 were being pushed out with Windows 7 x64 preinstalled.
So what, then, do you get for running a 64-bit OS? We've covered some of the advantages brought forth by the newer architecture, including granting one's system the ability to process more memory—up to a theoretical limit of 16 exabytes, technically.
