Hi,

There is no difference between unactivated over activated and unactivated after setup.
If computer keeps in unactivated status, it is available to use as activated in 30 days. After that there are restriction on some features and settings such as you can't change personalization, update system and others. Also the watermark about you should activated will appear on desktop.

For activation your system, we also could type "run" in Windows search box and input "slui.exe 4" in Run box to have a phone call activation.

For more measure about activation, please refer to the link below:

Hello,

Locate your product key using this support article:

Once located, go to Settings > Update & Security > Activation > Change product key. Type your product and re-activate.

Hope this helps!
