What is VPN?
VPN stands for Virtual Private Network. It allows the employees of an organization to access their company's private network securely over internet while working from another location. If effectively creates a tunnel that extends from your computer to your company's private network. Thus, no one can see from outside what exactly is going through that tunnel. This way the employee can access the resources which are only available on the internal private network.

VPN is also being used for other purposes like,
- Unblocking blocked websites
- Hiding your real IP address from other websites you visit online
- Bypassing geographical restrictions imposed by internet companies like Netflix
When using the VPN for purposes listed above, you connect to a web server provided by a VPN service provider. The requests made by your web browser software such as Google Chrome are first encrypted and then forwarded to your VPN service provider. Your VPN service provider fetches the requested data (webpages, files etc.), encrypts it and then sends it back to you. The websites you visit see the IP of the web server of VPN service provider, not your real IP address. Thus, the websites are tricked into thinking that you are from US where actually you could be from Germany.
What is OpenVPN?
OpenVPN is an open source software written by James Yonan first released in May 2001. The OpenVPN software application takes care of tasks such as connecting your computer to your VPN service provider, encryption, authentication, security and so on. OpenVPN supports many platforms and can run on Linux, Windows, Mac OS X, iOS, Android and more.
VPN Service Providers
To connect to your VPN service provider using OpenVPN, you would need OpenVPN configuration files, and username/password from your VPN service provider. ExpressVPN, CactusVPN are some big VPN service providers that have web servers in many countries around the world. These VPN service providers charge around $5 to $15 per month.
How to Install OpenVPN?
Let us now look at installing OpenVPN on Microsoft's Windows 10 operating system. The process of installing OpenVPN on other versions of Windows is similar.
Follow the following steps to get OpenVPN installed and running on your Windows 10 PC.
