As you have W10 home you may have issues as it has limitations, but certainly you could watch and if necessary take over control of the second computer using Quick assist, provided the software is registered under different microsoft accounts. I actually help a 79 year old ten miles from me on a regular basis now using just that method. You type quick assist on computer A in the search bar bottom left, select run as administrator, then when window appears choose 2nd option and request a code to help someone else. repeat the process for computer B but select option one this time. Go back to computer A code generated on A insert on computer B who will then have to allow access from computer A. That way one can always monitor B and intervene if necessary.
