Absolutely Free
Linux is a free operating system both in terms of pricing and licensing. You can download and install it for free and you can even modify Linux OS, make copies of it to distribute it to your friends, family and colleagues.

Revive Old Computer
Don’t throw your old computer just yet. Linux has got your back when it comes to low end configuration system. Some Linux OS can run on a system with just 128 MB RAM.

Safe & Secure
Linux is renowned for its security. You don’t even need an antivirus in Linux, just keep your system updated. Oh! and there are no hidden trackers to invade your privacy and steal your data.

Thousands of Applications
Linux has thousands of open source applications available to use for free. You can browse the software in software center and select the ones best on ratings and reviews. You also have a number of proprietary software available for Linux.

Customization
If you like tweaking the looks of your operating system, you’ll love Linux. With icons, themes, Conky, panel, dock launchers, you can customize the looks of Linux desktop in every possible way you can imagine.

Community
Linux project itself has been built around a vibrant community. When you are in need of help, you can get a variety of support in the form of documentation, forums and live chat.

Absolutely Proprietary
MIcrosoft's Windows operating system is 100% proprietary non-free software which makes it all the more difficult to trust running on your personal computer.

Requires Modern Hardware
Microsoft Windows now requires that you have the most up-to-date hardware with UEFI, Secure Boot and Firmware TPM 2.0. While the operating system can be patched to bypass such a strict requirement, that's still enough to drive most users away.

Unsafe & Insecure
Microsoft Windows has been and always will be the most vulnerable operating system for Viruses, Malware, Ransomware, etc and is often used by hackers and cheaters who easily exploit the operating system to harm or inconvenience other users

Lack of FOSS
While Linux has always provided Free and Open Source Software applications first hand, Microsoft Windows doesn't get that same treatment and you're often only able to find closed proprietary software alternatives to the free and open counterparts. Be ready to pay for your office suite and creative software!

Lack of Customization
This is already obvious enough. Microsoft Windows only allows you to change your wallpaper, so long as your product key is valid and activated. There's no such thing as themes on Windows anymore.

Lack of Community
Users of Microsoft Windows generally do not care or even acknowledge they are running Microsoft Windows on their personal computers anymore. They are numb to it. To ask for help from the community is like asking a brick wall for advice. You won't be able to get anywhere, and Microsoft's tech support can only help you with the basics. Beyond that, you are alone.
