A leaked copy for Windows 8.1 Update 1 is now available for download for those who want to have an early glimpse into the feature lineup of the next major update for Windows. The ISO comes only in 64-bit form and brings several changes to Windows 8.1, most of which we’ve seen in leaked screenshots that reached the web recently. The full build string of the leaked ISO is 9600.16596.WINBLUES14_GDR_LEAN.140114-0237 and is exclusively compatible with 64-bit computers, but a 32-bit version would most likely leak anytime soon. Of course, keep in mind that since this is an early build, it could be very unstable and a number of bugs could affect the overall performance on your computer, so if you don’t have the time for testing purposes, you better wait for the official release scheduled to take place in March.
