For some reason, sometimes File Sharing in the System Preferences (the Sharing pane) will turn itself on, every few days. I use File Sharing, but usually keep it off since upgrading to Mavericks, because it prevents Mavericks from going to sleep. I use it to share files with my PC, which runs Windows 8.1 and is on the same Ethernet home network. But for some reason, it decides to turn itself on every few days for some reason. Anyone know why it does this? I don't know if it's a Mavericks problem specifically or not, because I used to always keep File Sharing enabled all the time. But as I said, I have to turn it off now when I'm not using it, because otherwise my Mac won't sleep, since upgrading to Mavericks.
