Windows 10: Windows 10 Pro is convinced that my PC is connected to an organisation, and won't activate...

I bought a pre-built pc around 6 months ago, with windows 10 pro pre-installed. Around three months later, I see the "Activate Windows" watermark on my screen. In settings, it tells me "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: 0xC004F074. This is a personal PC. It has never been connected to an organisation. Please help!

Thanks

:)

Windows 10 Pro activation (connect to organisation)

After my windows 10 automatically updated I received the msg "your windows license will expire soon you need to activate windows in settings" then when I go to settings it shows in activation " windows is activated using an organisation's activation service"

I tried using my key in the window that shows after clicking "update product key" but it gave me this msg:

" we can not activate windows on this device since we cant connect to your organisation's activation server. Make sure you're connected to your organisation's network and try again. If you continue to have problems with activation connect to your organisation's
support person.(0xc004f074).

What is my organisation? and what do I do?
