I’m sure you know by now that there are many great free software out there that you can use without violating any copyright laws. I will try to review what I feel is the best in each category.
Operating System
If you are looking for an alternative operating system other than Microsoft, try Ubuntu (http://www.ubuntu.com/). Ubuntu has been one of the rising stars of Linux for home use. With its ease of installation, and wide range of drivers supported, it has gained much popularity for first time linux users. Their reputation has been enhanced with their recent announcement with Dell to offer the latest Ubuntu 7.04 on selected desktop and notebook. And Ubuntu promises to be also available free-of-charge.
Ubuntu itself comes with a great number of software ranging from office suite to internet browser, email software, graphics editing software, among many others. It has a very good documentation and ‘unofficial’ user guide giving detail instructions on how you can download more legal software for use.
The following section will be devoted to free software for Microsoft Windows Operating System. You might want to know that all the software I mentioned here (with exception of the email client as I have my own personal webmail software), I am personally using it.
Office Suite
The best and the greatest of the free office suite is without doubt the OpenOffice.org, especially with their latest version 2.1 (http://www.openoffice.org/). The problem many people have when trying to switch from Microsoft Office to OpenOffice.org 1.0 was that many of the shortcut commands are different. In OpenOffice.org 2.1, they have made many repetitive tasks like ‘copy’, ‘paste’, ‘cut’, etc. to use the same short cut as Microsoft Office, thus making it easier to switch. OpenOffice.org has also been adopted by many government agencies worldwide, further proving the value of the software.
Anti-Virus
My personal favorite here is the Avast! Antivirus v4.7 Home Edition (http://www.avast.com/). It has a high level of protection, with almost daily update of signature files, and build-in email protection. I have no problem with the signature update which I believe is crucial for up-to-date protection.
Internet Browser
Mozilla Firefox (http://www.mozilla.org/products/firefox/) is the first to introduce tab browsing, which in my opinion changes how people surf the Internet. With tab browsing, no long am I left with endless open windows, but I am able to switch from one page to another easily. Tab browsing is not the only reason why I choose Firefox, it is also more stable and secure than the other major browser.
Email Client
No Microsoft Outlook? Sick of Microsoft Outlook Express? A capable replacement is the Mozilla Thunderbird (http://www.mozilla.org/products/thunderbird). It has very good functionality, almost as good as Microsoft Outlook. And if you are using it to download your pop3 emails from your Internet Service Provider, it is an excellent software.
Graphics Editor
I want to highlight two software here, as I find both to be complementary to each other. First up is GIMP (http://gimp-win.sourceforge.net/), which is an excellent graphics editing software. I used GIMP and Microsoft Paint to open the same file, and did a minor editing on the graphics, and save them both in the same format. The one I save under GIMP always gives me a better resolution. I am not a professional graphics editor, but use it to edit my graphics that I use for my websites, and I am totally convinced that this software is a top quality graphics editor. If you need Scalable Vector Graphics format, Inkscape (http://www.inkscape.org/) will do the job for you. It might take some learning, but it is time well spend.
Archiver Software
While Microsoft Windows’ File Explorer comes with basic archiver function, 7-zip (http://www.7-zip.org/) has been my preferred choice. It is able to read almost all kinds of archiver formats and is a great addition to your arsenal of software.
FTP Client
If you are into setting up website, and need a good FTP client, try File-zilla (http://filezilla.sourceforge.net/). It has all the functions you need for a FTP client. Or if you are running Firefox (which you should), you can download FireFTP (http://fireftp.mozdev.org/), which is an add-on for Firefox.
PDF Creator
I previously recommended PDFCreator (http://www.pdfforge.org/products/pdfcreator) as the best PDF Creator software I have used, but recently found out when I upgraded to Windows Vista that PDFCreator is currently not support for Windows Vista. An excellent alternative will be CutePDF Writer (http://www.cutepdf.com/Products/CutePDF/writer.asp). Like PDFCreator, it install itself as a printer so you can print any pages from any program to a PDF format. If you are thinking of photocopying a document to file up as a backup, or printing out confirmation pages to keep, why not file them up an electronic copy instead and help save the trees (and $$$ for the paper and ink)!
I am also currently looking at another Vista-abled PDF Creator called PrimoPDF (http://www.primopdf.com/). What I like about this software is that you are able to set securities for your PDF file, excellent for E-Book publisher, as you can prevent your PDF file from been printed or copied. Again, it install itself as a printer so it is very convenient.
Disk Encryption Software
If you have a need to encrypt certain confidential files in your desktop or laptop, TrueCrypt (http://www.truecrypt.org/) does this nicely. You can create a virtual encrypted disk, encrypt an entire hard disk partition, or even encrypt an external storage device like a USB Thumb drive.
Text Editor Replacement
While Notepad by Microsoft serves as a good text editor software, I find myself using contantly installing EditPad Lite (http://www.editpadpro.com/editpadlite.html) whenever I install/re-install a new computer. Why? EditPad is really “lite†on resources, quick to load up, and can handle multiple files (using tabs), great if you are editing multiple text files at the same time or comparing different text files.
You can see that there are some very good free software out there, so the next time you intend to shelve out your money to buy a software that you need, check out and see if there are any equivalent software that you can get for absolutely nothing.
