Hello, I read the excellent thread "Windows 8 forced re-activation, if hardware changes", but did not want to resurrect it. There are still many lingering questions regarding what hardware triggers re-activation and how much activation real-estate you have. Since maybe the only reliable way to get answers is to experiment it's clear we need some methods to keep track of activation, which is now automatic. So, a few of questions of my own: 1) Windows 8 activation is now automatic (no "grace" period), but what about re-activation dues to hardware change, is that automatic also? I use windows in a VM (virtualbox) and fiddle with the settings a lot, I hate to think that windows might be secretly wasting re-activations without even letting me know what triggerred them. For example, I changed the amount of RAM to a lesser value and windows remained active, could it be that it got de-activated and re-activated automatically? Also I'm installing and rolling back drivers - than can also be a problem. 2) Regardless of the answer to (1) there should be a way to query number of activations made with your key. I heard about SLMGR /dlv which displays the 're-arm count' but I'm confused by the terms involved. I have the 'standard' 64bit ISO (not Enterprise, not VL, not N or anything else) and a Pro key. Is that a 'MAK', or is a MAK something different? Do re-arms only apply to MAK's? What does 're-arm' mean anyway? Is it the re-activation that occurs after a hardware change (the thing I'm interested in), or is it the process of postponing activation (like in previons versions you had 3 x 30 days = 90 days trial)? Thanks in advance to anyone who migh clear up things.
