NOTE: this is original M$ MSU files. GDR - General Distribution Release Spring 2014 Update - it is official term. 06|03|2014 -=W.Z.T=-
This is the Spring 2014 update for 8.1 RTM. They were briefly available for download by doing a registry hack, but MS has since taken the 2919355 down. We have verified these MSU files to have the same SHA1 hash.
