Ubuntu has always made things easier, but there are many users who are fond of few applications that run only in Windows. I always keep switching to Windows only to play Counter-Strike. If it is the same with you, then you can try out Wine. Wine is a free and open source software application that aims to allow applications designed for Microsoft Windows to run on Unix-like operating systems. Wine stands for Wine Is Not an Emulator.
With Wine installed, you can run Windows applications (.exe files) such as Adobe Photoshop, Microsoft Office, Call of Duty, Auto CAD, etc. The Wine App Db gives you information about the compatibility of applications. You can also try out the applications that are not listed in the App Database and then let others know about your user experience.
You can install wine from your terminal by typing the following into it.
sudo add-apt-repository ppa:ubuntu-wine/ppa
sudo apt-get update
sudo apt-get install wine
You can also install Wine from the Ubuntu Software Center
Running an application
Download the .exe file. Right click on it and then click on Open With Wine Windows Program Loader. Proceed in the similar fashion that you do on Windows to install a game or application.
After you have installed it, you can find the application’s shortcut either on your desktop or applications menu.
People who still use Windows just to run few applications or games can give it try.
