Linux and Windows are two different types of operating systems for web servers, with Linux being the most popular. It is estimated that around 70% of websites are hosted on Linux servers.
Since Linux based hosting is more popular, it has more of the features that web designers expect. So unless you have websites which need specific Windows applications, Linux is the preferred and recommended choice.
Linux is the operating system of choice because Linux hosting is well suited for blogs, content management systems, online stores and forums.
It does not matter whether your PC uses a Windows Operating system or not, as any device can communicate with a Linux website or a Windows website.
