Get access to my work pc from a laptop?

Does anyone know how I can get access to my work PC from my laptop so that I can open files from there and use them on my laptop?

Via "remote maintenance" and there are programs for, such as the two top dogs AnyDesk or Teamviewer

You will have to have your company's IT set up a VPN connection for you.

Where is your "work PC"? At work? If this is not just a ten-man dump, then the administrator should be able to explain and set it up for you. Also, for example, that work data has not lost anything on private computers. And when it comes to home office, the work company has to set up a home office computer for you.
