I activated windows 8.1 pro 32 bit with WMC, using a standard KMS activator. Then I brought up the windows wizard for phone activation. I gave in the numbers that appeared on my screen, and then entered into my computer the numbers they read off to me. And it seems to have worked. Now, what does this mean? Do I now have permanent activation? Or was this just another temporary activation, done the hard way around? Correction: it seems that the option for phone activation was not a result of my KMS activation, but rather a result of my subsequent attempt to activate with a MAK key. Windows told me that the key didn't work, and I should try another one, but apparently it did work enough to enable phone activation. I tried phone activation on a different computer that has only KMS, and the phone option was not available.
