Features:
-Non-Activated and Pre-Activated indexes. Take your pick.*
*Uses custom KMS folder in Windows directory. I've included the uninstall
script if you want to use a different activator later
-Highly Compressed install.esd recovery compression format.
-DaRT 8.1 integrated into boot.wim recovery options. Choose Repair
your computer, Troubleshoot, then MS DaRT options to open. Features
include an offline defender a/v scanner, password reset tool, registry
editor, offline hotfix removal, system file checker, and many more.
-UEFI boot information added to ISO boot data

Notes:
-All indexes use original MSDN 9/9 Win8.1 isos with integrated hotfixes.
-Added ei.cfg to sources directory. You *HAVE* to extract the iso and
delete the file if you want to upgrade from a previous version of
Windows. Use the win81-pkeys.txt on the ISO for install keys.
-This version uses qad's v6 KMS server service build with integrated
WinDivert functionality from Windivert 1.1.1 WDDK.
-Seems to fix the rare occasional setup bug where setup stops at 95 or 97%
I modified my export to esd method to include extra integrity check data.

Credits:

*Honestly, many more people worked on the project, but I can't name
them all. There's too many.
