Where to ask code question and hardware advice

Choroid

This post is about a hardware issue so if I am in the wrong place please provide directions. Same for code questions?
I have a W7 machine and long ago I created a MS account which I seldom use.
Now I have a W10 machine that a technician reinstalled W10 pro with MS Office pro
in the process he logged in to my MS account with my credentials.
OK so I am on the W7 and tried to log in to my MS account it tells me that the
Dell 7920 with W10 belongs to my account and that to add the Dell 7600 with W7
MS only option is to delete the Dell 7920 from my account. Not what I want to do!
So I tried live chat and they locked me out because I am sure I have all cookies blocked in Chrome tried FireFox not sure about cookies setting
Any way how do I add the W7 or support two computers with one MS account ? FWIW this config uses 1 monitor that auto selects the correct HDMI port

Control Panel -> User Accounts -> Manage User Accounts on the w7 device. You do not have to remove the w10 device.

@CharHen When I select Manage User Accounts I do not see any options for a MS Account. I do see a MS_VS_Liveshare listing under generic credentials
Under Windows Credentials "No Windows Credentials"

You could also try going to https://account.microsoft.com/devices, sign in and look for "Add Device"
