Something else to consider.
I'm not going to engage or debate in an ethical discussion of using pirated or software that has been cracked, but now with the advent of registering online, certain software companies can also attempt to probe your computer I would imagine to determine if you are a legit or registered owner.

One of my best friends uses a cracked copy of the latest Eudora program as well as a cracked copy of Norton Antivirus, and since all attempted "instrusions" show the originating IP address of the probes, in certain cases you can take that IP address, and just put (http://) in front of it in your browser address bar, and see the originating website. He has been probed by Symantec (makers of Norton Anti-Virus) as well as Qualcomm (Eudora maker)and others...but because he had Zone Alarm running they were able to discover didly.

Moral of the story: If you decide to use pirated software, (or borrow a friend's copy of something), 1st and foremost always run a complete virus scan on the zip files downloaded BEFORE installing the programs. (There is a version of Winzip8.0 beta in circulation that contains a virus.)

Secondly, if you have to give any information to a website in order to download any evaluation copies, always give them phony information such as email address, name, etc...and access these sites through an anonymizer program that will hide your true IP address, before downloading anything. This will also greatly reduce the amount of spam email you receive, since many of these sites sell or share all information that users input for downloading purposes.

Third, delete all your cookies after every internet session. (Just go into your Windows directory, find the folder called "Temporary Internet Files", click on the top file, and then scroll down to the bottom of the list and hold the SHIFT key down and click. This will highlight all of the files in the directory. Once highlighted, right click and hit DELETE.) Doing this within IExplorer - Tools - Internet Options - Temporary Internet Files - Delete -----does not get rid of all the cookies. The method encased in brackets here, does.
Fourth. If you find a program you really like and is useful to you, pay for it and register the bloody thing. This will encourage software developers to continue creating new and improved programs, apps, games, etc.

Personally there is so much crap software on the market, that I find it useful to download evaluation copies and see if the stuff is worth buying. I'd be skeptical about shelling out good money for programs that don't provide evaluation copies. Nothing is more infuriating than say buying a game you think will be good, only to discover that it is laced with bugs, or has a huge learning curve (thus rendering the enjoyment level of playing it to zero), or crashes or locks up your system.
