Windows 10: I've never purchased a Windows 10 digital license, but why is it showing Windows is...

Hi,I bought a used laptop from someone. Windows 11 was already installed in the laptop. I don't know Windows 11 was activated or not. By the way, there was no Windows activation watermark on the screen. A few days ago, I installed Windows 10 in place of Windows 11 in the same laptop. I downloaded the iso file of Windows 10 from Microsoft's official website. I did not enter any product key during the installation of Windows 10. But it is written in the activation tab that " Windows is activated with a digital license linked to your microsoft account". I do not know how Windows has been activate

Windows 10 Tweaks

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

Windows 10 upgrade license

Hello guys,

I have 1 license of WIndows 8.1 FPP/retail license. I want to upgrade to WIndows 10, but I one thing is unclear to me.
If I upgrade, will WIndows 10 license be retail or it will "turn" into some sort of OEM license?

I ask this because I upgrade my PC, you know, more memory, replace HDD, and I intend to upgrade the MB and CPU to Kaby Lake platform sometime in the future, (and of course sell the replaced hardware)
This thing is not clearly mentioned anywhere.

Thank you.
