Windows 8 password forgotten, detours?

Op
2

The following problem: I have a laptop that I haven't really used in about 8 years. When I opened it again because I urgently need it, it asks me for a user password. I have already read that you can open this password using OpenKey programs via CD and USB stick, but unfortunately I'm currently unable to do so because I do not have a second PC. So I wondered if I could somehow reset the PC, the data on the PC are not so important to me. Does anyone know a way?

Ch

If it is the Win-PW and you don't need the old data: install a new Windows after starting from CD.

Me

Insert the Windows CD, boot from the CD, completely erase the hard disk, reinstall Windows, reinstall and set up all drivers and programs.

Note:

You should write down all your passwords in a notebook so that they are still available at any time (even after years or if the devices suddenly fail).

And: what is in a notebook can't be hacked or spied on the computer.
