Hello Anthony,
Thank you for your message.
Is it possible to do this entirely remotely using Remote Utilities?
Yes, this is possible in case if you use
Host as it runs as a system service and allows to remotely control UAC prompt messages and perform administrative tasks on the remote computer.
In order to switch to using the Microsoft account, please open
Windows Settings and navigate to the
Accounts section ->
Your info tab, then select
Sign in with a Microsoft account instead:
Hope that helps.
