Last week I bought a Windows 8.1 laptop from the Microsoft store and set it up using my Hotmail account for login.
Today I had a 4 hour flight with no Wi-Fi service. When I tried to log on, it told me "Windows is offline, you should use the last password you entered." I put in my Windows password -- and it would not let me in. I tried entering it 15 times, I tried rebooting the computer -- nothing would work. I lost 4 hours of work time because I could not get the machine to let me in using my Microsoft account password while I was offline.
Once I got home and connected to WiFi, I could log in just fine. But: is 8.1 really designed to not let me log in when I have no connectivity? There are many places I take my laptop where I don't have access to WiFi. How do I fix this? I am an independent consultant who gets paid by the hour, so I literally lost hundreds of dollars when this happens.
