Windows 10: My laptop is asking me to activate windows and i activated long time ago

Hi, first of all excuse my english.


Today when i wanted to use my laptop it asked my to activate windows due to my license is not valid error code: 0xC004F012

I dont know what to do because i updated to windows 10 with the free license that microsoft gave long time ago, then i restored my computer

because i wanted it faster but now it asks me to activate Windows.

Also in Microsoft web it shows my device with Windows 10 CoreSingleLanguage and it seems to be activated but in configurations of my device it appears Home Single Language and is not activated at all.


I hope that you help me because this happened with no advice, actually, yesterday it was activated and i had no problem, this situation started today.

:)

 

Windows Activation?

Windows will do this if it detects a significant (their word, questionable use) hardware change, and will ask you to reactivate.

After a key has been activated X number of times, you will have to call to activate it.

Couple of tips for the phone call: You can use your keypad, and when they're telling you keys, instead of saying "Repeat that" and "Continue" type 1 and 2. With these tips, that activation call will only last you about 4 and a half minutes.

 

Windows 10 Activation (Insider)

I did a full clean install of Windows 10 a while back and it will not activate. I didn't do a clean install from Windows 7/8/8.1 it was from Windows 10 (activated) so I expected it to activate just fine since it was fine before hand.

My Windows 10 license wasn't created from a previous Windows 7/8/8.1 key I got it from signing up to be an insider back in Nov of 2014. I installed a preview build on my laptop from the insider program and it worked just fine and it automatically upgraded to newer and newer preview builds and then to the full release automatically, fully activated and working fine. I did a full clean install not long ago (expect it to go through without issue since it was working before) and now it will not activate and I can't find any info on how to get it to activate and I can't seem to find the insider Windows 10 key.

Microsoft online support was useless and the gave me the toll free number to tech support.. I am currently on the phone waiting, they said it could be a 1hr 30min wait.. sigh.. Any help would be appreciated. Thanks.

 

Windows 10 Activation (Insider)

This is exactly what I'm seeing and am still investigating. I don't want to get your hopes up though, as I think you're out of luck, unfortunately. I might be too, but I'm in with a chance and here is why.

I installed my Insider copy right at the start of the program on VMWare Player where it activated with my Live account. It also upgraded to the RTM copy when it was released and is activated. So far so good.

I then downloaded the ISO using Microsoft's tool and installed a clean copy on my laptop, again logging in with my Live account, but it won't activate, just like you've seen. Reason given is that the key is blocked. However, what I'm now gonna do is image that VM onto the laptop's HDD and see if that works. It may remain activated (doubtful), require a phone activation or simply not activate at all. Let's hope it activates.

BTW, I never opted out of the insider program and am still on the Fast updates, so my OS version is currently showing as 10.0.10532, which is later than the 10.0.10240 RTM build - it did a full OS install for it.

Finally, even though you can't activate yours, you can still do the upgrade thing from W7 or W8/8.1 so you're not actually stuck, you just don't get the Insider version.
