I am not sharing files with another computer/s or network. I went to "sessions" in the "shared folders" under "system tools" and there are no items. However, when I shut down the computer, I got the same message: "Other people are logged on to this computer. Shutting down windows cause them to lose data. Do you want to continue shutting down?" Any further idea/s? Thanks - ramon.

If you have more than one profile on that machine it just means that there is another profile logged on.

I only have one profile.
