I lost my activation status after attempting to reinstall Windows 10. This was the same system (no hardware changes) I've been testing previous Insider Builds on since the very beginning of the Insider Builds Program. Microsoft promised to honor everyone a free copy of Windows 10 (with license associated with Insider E-Mail Address) when RTM unleashes and I was permanently activated by the time Build 10240 came out. Yesterday, I went from 10240 to 10595; and I thought it would be a good idea to do a reset immediately after going to 10595 I did the Reset Method through the Recovery Option in Settings. From the description, it sounded like Windows was going to do a clean install (which it did), but deleting the OS and personal files on Local Disk (C). Shouldn't have altered the activation status since I never made hardware changes. After attempting to get the activation working, I winded up getting the USB Tool from the Windows 10 website, and did a so-called upgrade from 10595 to 10240, but the activation status did not resolve itself. I went through recovery options again and "Reset this PC" = No Change Getting through Microsoft Support is hit or miss; their phone support states over 90 minutes wait time followed by "we are now closed" ; absurd, shame to Satya Nadella for making a mess of the whole process; failed to make a streamlined solution. I had my legitimate copy of Windows since I've been an insider since beginning of this year. Microsoft promised every Insider, prior to mid-July, that their Insider Build versions would be considered genuine; reactivation wouldn't be necessary in any circumstances. I genuinely own this product Its absurd that I have to go through this activation mess.
