I'm considering getting windows 7 again and trying to upgrade again

Yes, I upgraded from Windows 7 Home Premium via Windows Update. I am not going to do a clean install until the activation issue is resolved. I am surprised Microsoft has not said anything yet, since obviously a significant number of users are having the same or similar activation issues. I do not know why Microsoft does not allow using the previous Windows key to activate Windows 10, seems way easier.

I have this same screen as the attached picture...
If this is indeed a generic key (which I have the same last digits of as well) I believe we are indeed screwed.
I called Microsoft.
Apparently, after you upgraded from your old OS, you were supposed to go into the Activation settings and manually hit the activate button, and possibly even have to sign into a Microsoft account. Your Windows 10 product key is tied to your mobo's BIOS, and this is what triggered that pairing...
If you were like me and you thought Windows was smarter than that, you took that generic key given before activation and tried to use it on a brand new clean installation.
You were also to NOT enter a product key during the Windows 10 clean installation, and were to wait until you got into the Desktop to later activate it...
I was told I would NOT get a unblocked key unless I reinstalled my valid version of Windows 8.1, updated it all the way until the latest update, and then upgraded to Windows 10 AGAIN. Then manually activated it in the upgraded 10 installation, then clean installed onto the PC, without activating until I got the the desktop and activated it in the setting manually using to product key...
These are some crazy hoops to jump through. I jumped through them all, and tripped through the steps apparently.
What the actual F\/<k Windows?
Time to grab either a $20 HDD and waste 4-5 hours doing this all over again or pay up $119.99 for a windows 10 license...
If anyone else hears or discovers otherwise, please let us know!

Windows 10 Activation Headache
It seems Microsoft dropped the bomb again, the issue with the activation of windows 10 should have been an easy fix... actually it just shouldn't have happened in the first place. And then to tell us we might have to buy a new key....wrong answer, if the OS is suppose to be free why would you pay for a new key? I did a clean install with no problems, until it came to the activation part and as with everyone else I got the error message that said my key has been blocked, why when I was using it before the clean install? I've read many forum post on this issue and have yet to find an answer, except to go back to windows 8.1 and just wait for Microsoft to get their act together. Waiting 24 to 48 hours for the activation servers to kick was also a waste of time, it did nothing. It's now been over 96 hours and still can't get it to activate. To anyone who might have a solution, I"m willing to try anything, except to start over, way too much trouble.

Hello,
I Used the Media Creation Tool from Microsoft to Upgrade the OS and all went smooth, the activation went ok.
The Drive partition were changed by the Upgrade progress, there was a secondary Hidden System Recovery applied; so i decided to run a Clean Installation of Windows 10 (Clean means Format from media, Partitions scheme from scratch).
During a Clean install Windows 10 create a reserved system partition of 500MB (windows 8 creates a 350MB), all went smooth and the activation was done after loggin in whit my Microsoft account.
I had some problem locating which drivers to use for a good build before rolling out all the other software I use; and ofc i had to stop the auto updates to fix problems with the synaptics software being overwritten by the windows update; so in short i made several clean installations, all of them went ok and activated, all but the latest(yesterday), the latest was unable to activate.(edited for clarification)
I tried everything i found on the web without success, and i checked the page on my microsoft account and i found a problem(I think), there were 2 instances of the laptop registered and not one, both with different hostnames(its random named you got from the installation); so i thought there was a problem on activation caused by the clean installations, and i made a full reinstallation process from windows 8 pro > 8.1 pro > upgrade to windows 10 and now the OS is activated again; before the reinstallation I removed the registered devices from the Microsoft account page.
I made attention this time to the hostname i gave to the laptop(weird, I thought microsoft just bind the licence to the hardware, I'm just confused) and now its enlisted correctly on the account.
The system is now back on my controll and activated, I have 2 reserved partition, 1 of 350MB from windows 8 installation process, and a new 450MB reserved partition from the upgrade.
Before trying again a clean install i would like to know(if somebody knows) if the DVD i just created days ago is not bind-created for the old upgrade or its just a RAW installation media that could be used again, or I need to recreate the DVD by running again the media creation tool inside the Windows 10 OS already activated.
I want to reinstall and have Windows to get its 500MB reserved without any need of extra partitions, and of corse i will install by using a local account, using the same localhost(computer-name) used for the upgrade; then switch to the Microsoft Account at the very end.
Edited:
I have started a Clean installation on my laptop, on the partition scheme i see the second reserved partition added at the system Upgrade to Windows 10, its 450 MB labeled as OEM (Reserved) while the 350 is labeled System; I had all the partition removed and its installing(fingers crossed).Last edited by Mocambo; 03 Aug 2015 at 11:23.

Seeing the same error code but the cause is different.
My Windows 10 was activated but now the activation status got REVOKED!
Windows Insider since Day 1 but my Surface Pro 3 had never installed W10 before July 29th. On 29th I took the upgrade offer on the SP3 and upgraded to W10 from 8.1. It was automatically ACTIVATED. Then I went ahead, created an ISO and did a complete clean install. After the installation the W10 was ACTIVATED automatically again. Woo-hoo! Sounds great huh?
Last night I was prompted that the W10 on SP3 was not activated. What? The activation status got revoked. When I go to Settings->Activation, the error code in the title of this thread is what I see. Phone activation does not work, though MS representative told me to wait for 48 hours; however having read all related threads and posts here I don't think waiting is a good solution to that.
Certainly don't have the time to do a re-upgrade and installation again; don't know what to do other than calling MS support.
I do like Windows 10, but it is really hard to accept how Microsoft screws everything into a mess.
