Auto Updates over a dialup connection

My sister lives back in the hills and does not have access to broadband. The best that she can have (and does have) is dialup. When she visits me, she will bring her computer and update Windows using my broadband connection. If she upgrades to Windows 10 Home, how is she suppose to get auto updates over a dialup phone line? The auto updates can be large and she would have to keep the dialup connection going for days. Is Microsoft forcing dialup users to remain on older Window versions?

Hey tron I just upgraded to windows 10 and have the exact same question. I know this is an old thread but did you get an answer ?
