Accessing startup boot options with Windows 8

With previous versions of Windows, the F8 key could be used during boot to access a list of startup options such as Safe Mode.  To access similar options with Windows 8, hold down the Shift key when clicking on the Restart option.






Another method is to use the shutdown.exe command with a new switch of /o.

sudo sed -i 's/NoDisplay=true/NoDisplay=false/g' /etc/xdg/autostart/*.desktop

All items should now appear within the Startup Applications dialog box.

Gow (Gnu On Windows) is the lightweight alternative to Cygwin. It uses a convenient Windows installer that installs about 130 extremely useful open source UNIX applications compiled as native win32 binaries. It is designed to be as small as possible, about 10 MB, as opposed to Cygwin which can run well over 100 MB depending upon options.


Multi Commander is a free multi-tabbed file manager that is an alternative to the standard Windows Explorer.


Tcpflow is a program that captures data transmitted as part of TCP connections (flows), and stores the data in a way that is convenient for protocol analysis and debugging. Each TCP flow is stored in its own file. Thus, the typical TCP flow will be stored in two files, one for each direction. Tcpflow can also process stored ‘tcpdump’ packet flows.

Tcpflow is similar to ‘tcpdump’, in that both process packets from the wire or from a stored file. But it’s different in that it reconstructs the actual data streams and stores each flow in a separate file for later analysis.

Open Full Packet Capture (OpenFPC)
