I am a bit puzzled about the activators for MS Offioce 2013 available currently and their version numbers All are called MicroKMS activators One follows 3.10, 3,12 and i have even seen a 4 Another follows K10, K12 etc numbering sequence They all seem to be appended by the term CODE3H Can thuis be sorted out for me? Are these the same of different - How? Is more more effective or perhaps earier that the other Thanks
