Windows 10: Windows 10 activation on a new computer

I built a new computer and installed Windows 10 on it. I'm not planing on getting a product key just yet. Windows is telling me that I have a product key which the last 5 characters match the "default" Windows 10 keys. I get an error code 0xC004C003. Has my computer done something with my account or another server, or does Windows just input those "default" keys if you haven't activated


Windows 10 Home 1909

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Click to expand... Yeah I went to that site, why do I need to buy a key?
I won't buy a key, stupid.

I'll revert back to windows 7 then.

When I still was on windows 7, about a year ago I added 4GB extra ram which is a total of 8GB now,
is that causing the problem?
