Hello. I have been having problems with my computer. A few minutes ago, when I tried to reboot, my computer informed me that my action could cause the other users (of my computer?) to lose information. No one is authorized to use my computer, but I had to unplug it to shut it down. Any help you can give to me will be appreciated.
