Switching between commercial and private use?

Hello everyone,

so I purchased a Remote Deskopt licence so I can use my Office PCs from home (Corona time...).

Now my mom would like my help at her private Desktop.
How can i help her without wasting her PC to one of the 3 licences?
Can i switch between private and commercial?
How do I deconnect "licenced" PCs?

Thank you in advance.
