4Moorhens2 4 years ago Using Windows 7 on a LAN or WLAN network may have serious security implications: user documents, including VIDEOS, might be seen, opened and modified by another pc (including a XP system) on the network (and beyond?) if one relies on the default "Share with > Nobody" settings. I set up a network and found it very difficult to prevent private user documents from being opened by another machine (in this case XP) on the network. Eventually (phew!) I discovered that it was necessary to right click on the Windows 7 C:\Users folder and make advanced settings from there. Now after resetting the permissions only the Public Folder can be seen and opened on the network (and possibly by an intruder, especially if only WEP wireless encryption is used.) Anybody with a single machine connected to a router via an ethernet cable or via wireless may not be aware that their private documents including VIDEOS may in fact be Public on the network.
