Windows 10: Lost Windows activation overnight - "Activate Windows" text in the right bottom corner of...

I have now owned this computer for about 2 years. I have always had Windows 10 Pro activated on the PC, but for some reason today when I wanted to login and play some games, a text in the right bottom corner of my screen says "Activate Windows - Go to Settings to activate Windows.". It seems as if I have lost my Windows over the course of some hours.


I bought this computer on a Swedish website called "Blocket", it is basically the same as eBay or Craigslist. Everybody can put up things for sale and then you can contact them to buy their products. I bought this computer after thoroughly checking it through and it had a valid activation of Windows 10 Pro.


I would greatly appreciate some help, since I do not know what the problem is. I don't have that much information about my Windows, other than the Product Key Channel is Volume:GVLK and that I get an error message and code in the Activation setting in Windows that reads: "We can't activate Windows on this device because we can't connect to your organisation's activation server. Make sure that you're connected to your organisation's network and try again. If you continue having problems with activation, contact your organisation's support person. Error code: 0x8007007B.".


If anybody have some insight on what my problem is and how I can fix it that doesn't involve spending 230€ on another copy, please do tell in the comment section. Thank you for your time.


If there is anything you need me to do to get more information about my problem, just ask.

Windows activation . . .

In the Windows activation status page is it still showing as activated, or do you have something like 3 days to do it in?

 

Windows Vista Activation

I have 4 sytems in my home running vista(1 ult.-3 prem).The ultimate & 1 premium took SP1
wthout a hitch.1 premium required re-activation?,The other premium did not list SP1 in windows up-date,So i manually installed it without any re-activation required.
Also have to add that SP1 has increased performance in every comp.The ultimate machine actually got a 1,100 point increase in 3d 06 without any other changes at all.

 

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.
