:: Windows 10 Hardening Script | |
:: This is based mostly on my own personal research and testing. My objective is to secure/harden Windows 10 as much as possible while not impacting usability at all. (Think being able to run on this computer's of family members so secure them but not increase the chances of them having to call you to troubleshoot something related to it later on). References for virtually all settings can be found at the bottom. Just before the references section, you will always find several security settings commented out as they could lead to compatibility issues in common consumer setups but they're worth considering. | |

The following are some brief notes about the changes that have taken place | |
since the release of the "Attacking JavaScript Engines" paper [1]. In | |
general, no big conceptional changes have happened since. Mitigations have | |
