"The problem is, for me, and many other developers, administrators or just normal users, that if you want to use applications from a different OS, you have to reboot and boot into the other OS. Sometimes, when you, for example, just want to do a quick test of a newly compiled application, and go back to work, it is very inconvenient and time consuming. Standard ways of dealing with these problems is either creating virtual machine for Linux, setting up two PCs (one with Windows, second with Linux) or using Cygwin/SFU (Services for Unix). But there is also another way, which allows you to run Linux on Windows natively - coLinux."
