My dad has not used his laptop for about 2 years and has no clue what his password is or have we already tried many things. Does one come in somehow to change the password then?
Depends on the type of password. Is it a BIOS password that needs to be entered before booting the operating system, or is it the password of the operating system user account?
In the latter case, it depends on the operating system. Under Windows, for example, there are several ways to bypass the password.
So it's windows 10 and it's just the password when he starts up and then comes the "lock screen". He does not remember the password anymore.
The easiest way:
Start with a Linux Live system, mount the laptop's internal hard drive, save all data to an external hard drive & then rebuild the laptop.
Attention: the data on the internal hard drive can only be accessed without a password if the hard drive is not encrypted (which will be the case 99%, so no stress)
Yes, the password of the Windows 10 user account can be changed or removed without logging in. For example, you only have to get system privileges.
Well… We have no clues, no microsoft account etc… Since you can't get a system rights, right?
Does one come in somehow to change the password then?
You can reset the password.
One way is z. B. Described here: https://www.pcwelt.de/...86600.html
At least up to W8, there are a number of freeware programs that do the job or just ask at Microsoft, there will be explained how to do that with "on-board resources".
If the user account used is a Microsoft account, you will find instructions here.

Otherwise, you can of course get on the lock screen system rights. Users with other rights have not been started yet.
But since I can't verify that it really is your father's laptop I can't give you any instructions here. All necessary information to find such a guide but you already have in my answers.
OK no problem. My father says he has important files, pictures etc on the laptop. If you z.b. The laptop reset (or what you call it), is the password still there?
If you reset the laptop, so reinstall the operating system, all data on the same hard drive or partition are normally deleted with. But at least you can then choose a new password.
Getting data from an unencrypted hard drive is even easier than bypassing the Windows password.
Remove the hard disk and connect it to another computer.
Alternatively, boot the laptop with a live system.
In both cases, you can access the data as well as any other connected media.
Yes on the new installation will run out because he has no important data on it. Do you have to buy a special cd then or does the "reset" mean that it is reset to factory settings?
Or is this the one cd that is always there when buying a laptop? Can I use the windows 10 cd of my acer for its hp?
You can reset it to factory settings, but depending on the type of reset, data such as user accounts and password will remain.
But "re-setting up" normally means a complete reinstallation. This can be done with a Windows 10 CD or with a Windows 10 USB stick. You can either buy them or create them yourself. You can download the required ISO from Windows 10 on the Microsoft side.
Yes, PCs / laptops have a corresponding CD with them. You can also use the Windows 10 CD of another computer.
