Microsoft recently revealed that we will be able to snag the Windows 8.1 Update 1 this Spring. Reports have stated that we will be able to download this update via Windows Update during the April 2014 Patch Tuesday. Specifically, MSDN subscribers will be able to snag the update on April 2nd, with general availability on April 8th. Now, according to the man behind the recent leaks of the update, Wzor, the highly anticipated update is now final and has been signed off. According to the build string, the build was complied on the 21nd of February. If we are lucky, we may see a leak of this build prior to the April rollout. Either way, we will keep you updated as things develop.
