Ever tried this query in Google: "Linux-like environment for windows" with inverted commas? If you have, it gives exactly 13,700 results (at the time of publishing). Now try the same other way around. Google "Windows environment for linux" but don’t use the quotes from previous query. It yields approximately 1,150 results. This clearly shows that there are numerous applications that simulate a Linux environment on Windows and vice versa. But are all these applications really required?
