Windows 10/11 Security Changes
November 29, 2023

These sites have some ideas on how to harden your security. They have a paid version that does it all at once. I have NOT tested their paid version.

This site is meant to be used as a reference for myself, although others may find it useful. I use it to keep track of certain fixes, software, and other solutions which I may need while assisting customers. The page layout is pure HTML/CSS and is kept simple to optimize loading time and fast results.
