Hi Lipstic,
Check in Task manager service section Service Name: "wlidsvc" shows up as Service Name: "Microsoft Account Sign-in Assistant" in the list of services for me. You May stop it untill that user session.
To disable it permanently type services.msc into the start search box and press Enter. This will open the Services snap-in of the console.
Then Check for Microsoft Account Sign-in Assistant >> double-click on it to open its properties dialogue. >> select “disable”from the drop down, then click OK. >> Restart your PC.
Let me know if this solution works for you. If not, please feel free to reply, and I'll be happy to provide further assistance.
Regards,
Kishen :)
