Change used computer unique numbers

[KW.]

I have a used Dell laptop and wonder if its possible to make that laptop to change everything. Mac adress i know you can change. But is it possible to change every other identifier on the computer that existed before I got it?

And is it enough to just do format on the drives and windows restore?

EDIT: I understand its identifiers on the hardware, but its on software my question is about

Nope. Not everything.
Are you trying to hide your activity or the previous owner ?
Bottom line , it can be traced back to you.

Im mostly curious how "new" you can make a old computer and what traces that exist in a computer or another software. But your answer is a bit of what I suspected I guess that is why "burners" is used when needed for both legitimate and illegitimate reasons.

Thanks @degrub

EDIT found this about some identifiers: https://www.nextofwindows.com/the-best-way-to-uniquely-identify-a-windows-machine

In terms of user software you could completely wipe the hard disk, including any hidden partitions like the ESP, recovery or OEM. That would be equivalent to installing a brand new disk.

But the hardware characteristics remain the same. You might be able to spoof a MAC address in software but the real MAC address is still there. In the BIOS/UEFI there are ACPI tables that allow the PC to be uniquely identified. This is how OEMs store the Windows licence key nowadays so that you don't need to read a product key off a sticker.

MAC addresses are like serial numbers, they are embedded into the hardware. The best you can do is have the software ignore it and use a different MAC when configuring the network, but that won't replace the hardware-burned MAC, and reinstalling the operating system will restore the original MAC.
