I came across this issue this morning on my home PC. I have a Windows 7 64-bit PC with three profiles, my wife's, mine, and my daughter's. Previously when someone tried to log in all three profiles would be displayed so each profile could be selected. However this morning instead of seeing the three profiles I see two options: the active profile and a button that says other users. I select other users and I can log on to any profile so nothing appears to be missing. If I power the system down, when it comes back up I see the last profile logged on and the other users option. If someone could give me an idea as to why this occurred and how to fix it I would appreciate it.
