HOW TO: Disable 16-bit Application Support, Disable MSDOS and WOWEXEC Subsystems

However, for simplicity sake, here is how you disable MSDOS and WOWEXEC subsystems in text format.

The images and processes listed below are for Windows 7 machines, though the process is almost identical for any version operating system.

What you are going to do is simply modify the security policy of the machine (or domain controller) to prevent access to 16-bit applications. This then disables the “DEBUG.EXE” process, which is what will effectively prevent the attack.

1.) Click START, and then RUN (if the RUN command is not visible in your start menu, simply right click on your start menu and customize the enabled features).

2.) Enter GPEDIT.MSC and press enter. (If you are prevented from accessing GPEDIT, you may not have security rights – OR you are using Windows HOME edition, which does not have this ability, and you will probably need to wait for Microsoft to release a patch)

Run an 16bit program on Modern Windows

That's a pretty old game. Realistically, there are limits on how long you can keep using old software. Eventually, operating system designers have to choose between backward compatibility and future capabilities.

And yet, if your program was created with Windows 98 primarily in mind, it has a reasonable chance of working in Windows 7 or 8. But if it was already old in 1998, or was written to be backward compatible back then, it will have problems with most current computers.

If your attempt to run or install the program gives you an error message that reads something like the one below, chances are you're trying to run a 16-bit program in a 64-bit environment. You can't do that.

How to Re-Enable Hibernate in Ubuntu 12.04

If you’ve just updated to Ubuntu 12.04, you may notice an option missing in its system menu. The Hibernate option is now hidden by default, but you can get it back if you prefer to hibernate your system.
Hibernate is disabled by default because it can cause problems on some system configurations. You should perform a hibernate with a special command to test that it works properly before re-enabling it.

How to Add a Taskbar to the Desktop in Ubuntu 14.04

If you’ve switched to Ubuntu from Windows, it may take some time to get used to the new and different interface. However, you can easily incorporate a familiar Windows feature, the Taskbar, into Ubuntu to make the transition easier.

How to Share Printers Between Windows, Mac, and Linux PCs on a Network

Windows, Mac, and Linux can all get along together, sharing files with each other on a network. They can also share printers, allowing you to use a single wired printer for all the computers on your home network.
This is only necessary if you have a wired printer connected directly to a computer, such as USB printer. Modern wireless printers connect to networks and share themselves, so you just have to connect to them.

How to Turn Off the Shutdown/Restart Confirmation Dialog Box in Ubuntu 14.04

By default, Ubuntu is configured to always prompt you with a confirmation dialog box with two choices when you want to shut down or restart your computer. The same thing happens when you log out of your account or lock your session.

How to Install, Remove, and Manage Fonts on Windows, Mac, and Linux

Whether you want to use a new font in a Word or just change your operating system’s system font to give it a different look, you’ll first have to install the font on your operating system.
The installation process makes the font available to all programs on your operating system. Most applications don’t allow you to simply load a font file and use it — they provide a list of installed fonts for you to choose from.

Macs also hide files and folders beginning with a . character. There’s also a special “hidden” attribute the Finder will obey. Hiding a file or folder is a bit more difficult on a Mac. Try to rename a file or folder so it begins with a period and the Finder will tell you “these named are reserved for the system.” There’s also no way to quickly toggle the hidden attribute in the Finder’s graphical interface.
You can quickly mark a file or folder as hidden with the chflags command in the terminal. First, open a Terminal window by pressing Command + Space, typing Terminal into the Spotlight search dialog, and pressing Enter.
Type the following command into the terminal, but don’t press Enter:

Hide a File or Folder on Linux

Linux hides files and folders that have a period at the start of their name. To hide a file or folder, just rename it and place a period at the start of its name. For example, let’s say you had a folder named Secrets you wanted to hide. You’d rename it to .Secrets, with the period in front. File managers and other utilities will hide it from view by default.

How to Configure the GRUB2 Boot Loader’s Settings

Ubuntu and most other Linux distributions now use the GRUB2 boot loader. You can change its settings to select a default operating system, set a background image, and choose how long GRUB counts down before automatically booting the default OS.
We configured GRUB2 on Ubuntu 14.04 here, but the process should be similar for other Linux distributions. You may have customized the original GRUB’s settings by editing its menu.lst file in the past, but the process is now different.

How to Fix an Ubuntu System When It Won’t Boot

Ubuntu doesn’t offer the Safe Mode and Automatic Repair tools you’ll find in Windows, but it does offer a recovery menu and a reinstall option that keeps your files and programs.
If you can’t boot anything — not even a USB drive or CD — you may need to configure the boot order in your BIOS. If this doesn’t help, there may be a hardware problem with your computer.

How to Boot Linux ISO Images Directly From Your Hard Drive

Linux’s GRUB2 boot loader can boot Linux ISO files directly from your hard drive. Boot Linux live CDs or even install Linux on another hard drive partition without burning it to disc or booting from a USB drive.
We performed this process on Ubuntu 14.04 — Ubuntu and Ubuntu-based Linux distributions have good support for this. Other Linux distributions should work similarly.

How to Change Your Hostname (Computer Name) on Ubuntu Linux

Ubuntu asks you to choose a name for your computer — known as a “hostname” — when you install it. You can change this hostname later, but Ubuntu doesn’t provide a graphical interface for doing so.
The process here will also work on Linux Mint and other Debian-based Linux distributions. Other Linux distributions — for example, Fedora and other Red Hat-based distributions — use different methods for specifying a hostname.

How to Easily Add and Remove Programs in Ubuntu 14.04

If you use Windows, you are probably familiar with the Add/Remove Programs tool in the Windows control panel. It lists the programs currently installed on your system and provides an easy method for uninstalling them with only a few clicks.

How to Remove a Password from a PDF File in Linux

You’ve protected a PDF file containing sensitive information with a long, secure password so only the intended party can open it. However, you don’t want to enter that password every time you access the document, so you want to remove the password from your copy.
We will show you four ways in Linux to remove a password from a PDF file when you know the password.

How to Install and Use a Mac OS X-Style Desktop Dock in Ubuntu 14.04

Have you switched from Mac to Linux and miss the Mac OS X-style launcher? Or, maybe you just want a dock other than the Unity Launcher on your Linux machine. Cairo-Dock is a customizable dock you can add to your Linux desktop.

Installing Microsoft Office With Wine

We tested Office 2007 with this process, as Office 2013 is known not to work properly and Office 2010 doesn’t appear to be well supported. If you want to use an older version of Office, like Office 2003, you’ll likely find that it works even better. If you want to install Office 2010, you may need to perform some more tweaks — check the Wine AppDB page for the version of Office you want to install for more information.
First, install the Wine package from your Linux distribution’s software package repository. On Ubuntu, open the Ubuntu Software Center, search for Wine, and install the Wine package.

Android Programming Tutorial

Android is an open source and Linux-based operating system for mobile devices such as smartphones and tablet computers. Android was developed by the Open Handset Alliance, led by Google, and other companies. This tutorial will teach you basic Android programming and will also take you through some advance concepts related to Android application development.

1. What is Android?

1. What is Android?

1.1. The Android operating system

Android is an operating system based on the Linux kernel. The project responsible for developing the Android system is called the Android Open Source Project (AOSP) and is primarily lead by Google.
The Android system supports background processing, provides a rich user interface library, supports 2-D and 3-D graphics using the OpenGL-ES (short OpenGL) standard and grants access to the file system as well as an embedded SQLite database.
An Android application typically consists of different visual and non visual components and can reuse components of other applications.

1.2. Task

In Android the reuse of other application components is a concept known as task. An application can access other Android components to achieve a task. For example, from a component of your application you can trigger another component in the Android system, which manages photos, even if this component is not part of your application. In this component you select a photo and return to your application to use the selected photo.
Such a flow of events is depicted in the following graphic.

combined into one icon!

7stacks is an easy to use, free app that lets Windows 7 (and Vista and XP) users have “stacks” of icons in their Taskbar (in 7) or QuickLaunch Toolbar (in Vista and XP). By using stacks, users can reduce icon clutter, and combine a group of related icons into a single icon. For instance, if you use application suites such as Microsoft Office, OpenOffice, or Adobe CS4, you can have all the suite’s icons combined into one icon!
