Thomas uses Windows 8.1 and he's having issues with the PIN log-in. Leo says that Windows offers a lot of ways for users to log-in, including Microsoft's ID. There's also the picture password. He can trace a pattern over the picture and he has a log-in. But if the picture password isn't working, and he has to use his Microsoft ID, that can be a pain. Microsoft isn't helping much, either. The issue may be that Thomas is using two monitors, and if he's using the picture password, it's touch focused and an extra monitor can confuse things. He should try the PIN.
