I am the IT administrator for a few branch offices, and am seeing more and more of our staff "accidentally" linking their account to a MS account. I did some searching on here and found out how to remove the ability to link to an MS account (What features of Windows 8/8.1 Pro will not work without a Microsoft Account?), but I am still not able to remove the link from their account if they leave the organization as part of the equipment return process.
How can I remove their account from being linked to an MS account if I cannot change their account password and login as them? I don't see the option in the Control Panel or PC Settings, even when logged in as an Administrator.
