What is Microsoft Reactivation Number?

[Isack]

Hi, a few months ago I upgraded my motherboard and CPU so had to re-install windows. When doing that i called a number to give them my product key so they could cancel it and give me a new one for my new platform. I have had trouble searching for this number and was wondering if anyone knew. Thanks in advance.

from memory you have to contact them by email and they arrange a time to call you..

this is the local one but you probably want one in country: https://support.microsoft.com/en-au/gp/cu_sc_prodact_master?wa=wsignin1.0
