Create a CD autorun file

If you have produced the contents for your CD and then want them to autoplay when the disc is loaded into a computer then you should add an autorun file to the CD. An autorun file is a simple text file that tells the operating system which executable file to start.

There are two main types of autorun file that you could use:

Autorun using the 'open' command

The open command is compatible with any PC running Windows 95 or later (although it is possible to manually disable the autorun feature on any computer, so if someone cannot view your autorun application then this may be a reason). However it can only be used for opening executable files ending in .exe such as Flash presentations, it cannot be used for opening documents such as Word files, PDFs or web pages. To open documents rather than executable files using autorun please look at the shellexecute command instructions below.

Running Multiple Instances of Google Talk

Users of Google Talk (GTalk) can also let GTalk go to polygamy, that’s running multiple instances of Google Talk and login to multiple Google accounts on Google Talk. The polygamy trick can be done without any crack, patch or hack, with just a simple command line parameter or switch /nomutex appended to the Google Talk shortcut.

Ability to polygamy running multiple Google Talk is useful if users have multiple Google Talk accounts (or Google or Gmail accounts that used to login to GTalk) or multiple profiles or personalities, and don’t want to log on and off from one account to another account every time when want to switch, or want to log in to all accounts at the same time on the same computer.

Resolve “Setup did not any hard disks drive” error while installing XP over a laptop

sometimes for compatibility reasons, but also because a lot of people just don't like 7 very much.
The problem that people keep running into left and right is getting to the point where XP starts to install and getting the message "Setup did not find any hard disk drives installed in your computer". This error happens because your new computer has a storage controller that isn't supported natively in XP, usually an SATA (Serial ATA) controller.

If you don't have a floppy drive in your computer (who does anymore), then you'll need to use a process called slip-streaming to integrate the storage drivers into your XP installation CD.
It should go without saying that this is an advanced topic, so proceed with caution.

Create a Zip Bomb - Zip of Death

A zip bomb, also known as a Zip of Death, is a malicious archive file designed to crash or render useless the program or system reading it. It is often used by virus writers to disable antivirus software, so that a more traditional virus sent afterwards could get into system undetected. A zip bomb is usually a small file (up to a few hundred kilobytes) for ease of transport and to avoid suspicion. However, when the file is unpacked its contents are more than the system can handle.You can make your own zip bomb to annoy your friends or just out of curiosity (or wilderness) to experiment with it. Make sure you don't detonate it on yourself.
