Close All Open Windows with a Single Click

This program lets you close all running applications with just a single click. It doesn’t use system resources because it only flashes a ‘close’ signal to all open applications on the desktop and then ceases. Just create a shortcut to the tool in the Start Menu, Quick Launch, Windows 7 Taskbar or elsewhere.

You can always add a hotkey to this shortcut. It is really very handy if you are running ~20 applications and want them all to quit instantly. It works just as if you were pressing the close button for each application.

How To Install

Close All Windows is a very simple utility that doesn’t require installation. No settings are stored in the Windows Registry or file system. Just follow the steps below to set it up on your computer.

      1. Download the ZIP archive and extract it somewhere on your hard drive.
      2. Open the extracted folder, right-click CloseAll.exe and choose Send To -> Desktop (create shortcut) from the context menu.
      3. Switch to the Desktop and rename the created shortcut to “Close All” or whatever you want.
      4. Now you can drag this shortcut to the Quick Launch Bar or to the Windows 7 Taskbar for quick access.

Advanced Options

If you want to prevent certain applications from being to be closed by Close All, you can add a simple exclusion list to the CloseAll.exe command line.

    1. Right-click the shortcut and choose Properties from the context menu:
    2. Go to the Shortcut tab, Target and add -x=”app-to-exclude.exe”:

You can separate multiple values with “|” (pipe), example:


Click OK to save the shortcut properties. Remember, you’d better test it before using it!

Scan a subnet for active IPs

With NMap it is quite easy to scan a subnet for active IPs.

$ nmap -sP

Install and setup Minicom

Minicom is the hyperterminal for Linux.

Minicom is by default not installed.

  1. Install Minicom with the following command

    sudo apt-get install minicom

  2. Find your serial port

    dmesg | grep tty

    $ dmesg | grep tty
    [    0.001251] console [tty0] enabled
    [   72.953237] usb 6-1: pl2303 converter now attached to ttyUSB0

    I use a USB serial port, my laptop doesn’t have a build in serial port.
    So the name of the serial port is ttyUSB0.

  3. Configure Minicom

    sudo minicom -s

    • Select “Serial Port setup”
    • Enter A to change the selected serial port, in my case change to /dev/ttyUSB0
    • Enter E to change the line speed to 9600 8N1
    • Select “Save setup as dfl”
  4. Exit Minicom
  5. Start Minicom with

    sudo minicom

And you are  good to go.

VirtualCenter Passthrough Authentication

Tired of login in into the Virtual Center Client?  Try this…

A very useful, yet very undocumented feature of the Virtual Infrastructure Client is that it can be configured to automatically pass your Active Directory credentials without you typing them in. To use: create a shortcut to the Virtual Infrastructure Client, then right-click on it and edit the shortcut properties. You’ll need to pass the program two arguments when calling it like so:

C:\Program Files\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\VpxClient.exe” -passthroughAuth -s

Where “” is replaced with the DNS name for your VirtualCenter server.

Tightvnc and Ctrl-Alt-Delete

I used Tightvnc today but didn’t remember how to send Ctrl-Alt-Delete to the server.

It was easy. Just hit F8 and click on Ctrl-Alt-Delete in the pop-up.
