I wanted to sell my laptop soon. If I reset the system so that my laptop is loaded again with the same features as I bought it the first time, then everything is deleted, right? I ask because it may be that you can fish with illegal software files
I ask because it may be that you can fish with illegal software files
There's nothing illegal about that. Such software is available as freeware or for sale (also in every electronics market)
If you want to be sure that nothing can be restored you should use a tool like DBAN. https://www.bsi-fuer-buerger.de/BSIFB/DE/Empfehlungen/RichtigLoeschen/DBAN/dban_node.html
Here is another video, which shows the topic quite well:
The "normal" deletion - and thus the reset does not delete any content. It only marks data as overwrite.
How to delete "correct":

with illegal software can still fish files
There's nothing illegal about such software. The type of use can only be illegal. There's nothing illegal about a hammer. Who kills one, but makes something illegal.
It is better to overwrite the hard disk with zeros. Best several times. To do this, download this ISO https://www.chip.de/...97298.html and use this tool to flash https://www.balena.io/...io/etcher/ onto an empty formatted USB stick.
Then boot the stick. Now a partition wizard is started with which you can partition hard disks, format and overwrite with zeros.
When that's done create a Windows 10 USB bootstick with the Media Creation Tool. So you can reinstall Windows clean. You do not need to enter the key, it is permanently integrated in the UEFI. After completing the installation, do not create a user account, but turn off the device. The new user then has a cleanly installed Windows. If he then creates a user account, Windows will be reactivated.
Well after the video, I can synonymous with no program to delete. Do not just press on fast formatting but the long formatting
