Please note that this is not a limitation of the Wireshark implementation, but of the underlying WinPcap driver see this note in the WinPcap FAQ. It might not be desirable that any local user can also capture from the network while the driver is loaded, but this can't be currently circumvented. Note: Simply stopping Wireshark won't stop the WinPcap driver! Once the driver is loaded, every local user can capture from it until it's stopped again.

The WinPcap driver (called NPF) is loaded by Wireshark when it starts to capture live data. If you are running inside a virtual machine, make sure the host allows you to put the interface into promiscous mode.
