Resetting Pc or Laptop Risks?

Moin people I wanted to reset my laptop to factory settings and wanted to ask what I have to consider. So when I reset it do I have to log in somehow? What do I do if I don't remember my password? Can I then create a new account?

Ne if you reset win10 then all files are deleted and you don't have to log in again if you mean a micosoft account.

So mostly you log in with a Micorsoft account if you have a Windows device. You can simply reset that or create a new account, when you reset all data will be gone. So be sure to save first!

So if you reset your PC all personal data will be removed and everything is back to the beginning when you bought the PC. You have to save all data that are important to you on a USB stick or another hard drive. After the reset you add everything again one
