I read in this thread that the leak of Windows 8.1 Update 2014 it's not the final version, but I ask myself if it's the same situation of the leak of Windows 8.1 that was updated with the GA Rollup, or if it's like a beta, that I'll have to uninstall when the official release will becomes available. Were found bugs in this version? I also ask myself if I install these updates I will lose the activation of Windows and Office via Microsoft Toolkit 2.5 (WinDivert system) and if I will be able to continue using it after the installation. It may serve, I actually installed Windows 8.1 Enterprise x86 full updated and Office Professional Plus 2013 VL. Sorry my bad English, and, if possible, please answer me by very basic English. Thanks!
