There is so much to go over regarding hardening an operating system and overall making a secure/stable network for your business or as an individual. For this topic I am going to avoid specific operating systems and primarily talk about a more generalized approach to hardening/securing a stable network and system OS.

First and foremost it is important and ideal to install a trusted OS/ISO to your system. This is important because without a trusted OS unwanted bloatware can be not only be system demanding (regarding subprocess's), but also vulnerable towards attacks. Also certain bloatware/subprocess can be malicious depending on the OS/ISO installed.

Keeping your system up-to-date regarding system patches/updates is also vital. This includes driver patches/updates and all application patches/updates too. This can be easily achieved by setting up automatic updates which is also recommended.

To continue, installing a trusted anti-virus and firewall will not only stabilize your system/OS but also actively keep it secured from threats/downloaded media. Being cyber-safe can also help with security as anti-virus and firewall applications are not 100.00% guaranteed to stop all malicious media/applications if installed.

Finally, the steps above are just a generalized approach to hardening your OS and network, but are the three most important steps (in my mindset) to achieve this.
