Windows merupakan sistem operasi yang umum diinstal secara bawaan ketika membeli PC atau laptop, sehingga secara otomatis pembeli mendapatkan Sistem Operasi Windows Original (legal) tanpa harus khawatir masalah pembajakan. Namun, kadang hal tersebut tidak dibarengi dengan keinginan untuk menginstal software lain yang legal karena alasan mahalnya perangkat lunak tersebut, misalnya Microsoft Office, SPSS, Photoshop dan sebagainya. Padahal sebenarnya hal tersebut tidak perlu terjadi apabila pengguna mengetahui perangkat lunak yang gratis (freeware) yang cara kerjanya kurang lebih sama dengan perangkat lunak yang biasa dibajak tersebut.

Freeware Sebagai Alternatif
Freeware merupakan perangkat lunak yang gratis, baik cara mendapatkan maupun penggunaannya, sehingga apabila pengguna tidak memiliki uang yang cukup untuk membeli perangkat lunak yang legal, maka pengguna dapat menggunakan freeware ini. Jangan pernah memandang rendah freeware, karena kualitas perangkat lunak tidak ditentukan dari gratis atau mahalnya perangkat lunak. Pada prinsipnya, semua itu ada kelebihan dan kekurangannya. Berikut adalah beberapa freeware yang dapat digunakan untuk mengganti perangkat lunak berbayar:
1. Libre Office sebagai alternatif dari Ms Office
LibreOffice is community-driven and developed software, and is a project of the not-for-profit organization, The Document Foundation. LibreOffice is developed by users who, just like you, believe in the principles of Free Software and in sharing their work with the world in non-restrictive ways. At the core of these principles are the four essential freedoms and the tenets of The Document Foundation’s Next Decade Manifesto [pdf]. We believe that users should have the freedom to run, copy, distribute, study, change and improve the software that we distribute. While we do offer no-cost downloads of the LibreOffice suite of programs, Free Software is first and foremost a matter of liberty, not price. We campaign for these freedoms because we believe that everyone deserves them. We seek to eliminate the digital divide and empower all as full citizens, support the preservation of mother tongues, and avoid proprietary software and format lock-in.

2. Gimp sebagai alternatif dari Photoshop
GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program for such tasks as photo retouching, image composition and image authoring. It has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc. GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted. GIMP is written and developed under X11 on UNIX platforms. But basically the same code also runs on MS Windows and Mac OS X. (sumber: http://www.gimp.org/about/introduction.html)
3. PSPP sebagai alternatif dari SPSS
GNU PSPP is a program for statistical analysis of sampled data. It is a Free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. The most important of these exceptions are, that there are no ‘time bombs’; your copy of PSPP will not ‘expire’ or deliberately stop working in the future. Neither are there any artificial limits on the number of cases or variables which you can use. There are no additional packages to purchase in order to get ‘advanced’ functions; all functionality that PSPP currently supports is in the core package. PSPP is a stable and reliable application. It can perform descriptive statistics, T-tests, anova, linear and logistic regression, measures of association, cluster analysis, reliability and factor analysis, non-parametric tests and more. Its backend is designed to perform its analyses as fast as possible, regardless of the size of the input data. You can use PSPP with its graphical interface or the more traditional syntax commands.

4.Inkscape sebagai alternatif dari Corel Draw
Inkscape is an open-source vector graphics editor similar to Adobe Illustrator, Corel Draw, Freehand, or Xara X. What sets Inkscape apart is its use of Scalable Vector Graphics (SVG), an open XML-based W3C standard, as the native format. (sumber: https://inkscape.org/en/about/overview/)
5. Mozilla Firefox sebagai alternatif dari Internet Explorer
We-ve always designed Firefox to protect and respect your private information. That-s why we-re proud to be voted the Most Trusted Internet Company for Privacy.How you use the Web is unique. Firefox lets you change it to match. Remove what you don-t use, keep what you do and put it just about anywhere you want. Firefox was named the ‘speed king’ in independent benchmark and performance tests against other browsers. Save time and do just about anything quicker than before.

Freeware Sebagai Pengaman
Ternyata, keamanan itu tidak selalu mahal, apabila pengguna tahu bagaimana caranya. Sebagian komunitas atau perusahaan dalam bidang perangkat lunak keamanan ada yang membuat freeware untuk keamanan komputer, meskipun beberapa freeware memiliki tingkat keamanan yang terbatas. Namun, lubang tersebut dapat ditutup oleh freeware yang lain. Sebagian besar masalah yang dikeluhkan oleh pengguna Windows adalah banyaknya varian virus yang muncul dari waktu ke waktu yang perilakunya sangat mengganggu. Entah berapa besar invenstasi dosa yang dibuat oleh pengguna virus itu selama virus itu berkeliaran, maka bertobatlah wahai pembuat virus. Berikut adalah beberapa freeware yang dapat digunakan sebagai pengaman:
1. Comodo Firewall untuk firewall dan anti-exe

3. Ninja Pendisk untuk keamanan flashdisk
Ninja is the popular and freeware program designed for guarding computers against viruses transmitted by USB pendisks. This ninja awaits quietly in the system tray for the times whenever a USB pendisk is inserted on the computer which will be examined to uncover the commonly malicious or virulent files known as ‘autorun.inf’ and ‘ctfmon.exe’ amongst many others. To keep things simple, ninja is fully portable, self-contained and requires no installation. Besides removing known virulent files, this tool will also immunize your pendisk and create a folder called autorun.inf with special protection permissions to protect your pendisk from being infected again when plugged on contaminated computers.
