Since i‘ve been doing this sort of thing for many years here are some basic rules: - Get LTSC (W10) or IoT/Enterprise (W11) images to begin with - Get https://www.ntlite.com/ .. you won‘t find any other tool which does a better job at removing packages, adding drivers, etc. Worth every penny with great support. - Use GroupPolicies to configure your system. Take the time and download them for Office, Edge, Chrome, Firefox and update those that come with Windows. - Integrate drivers not only for the base image but also in the recovery and setup image. - Install a firewall (binisoft is fine) - Use NextDNS - If you don’t mind the security implications: Disable Defender, SmartScreen, BootGuard and VBS (use bcdedit) - Disable Microcode loading (delete the DLL) - Disable Spectre/Meltdown mitigations - If you need Office: Use the LTSC version
Most third party tools are outdated or do stupid stuff which isn’t needed. You can silence Windows with the right GroupPolicies quite easy.
No one should follow those suggestions. They’re wholly unnecessary and plain bad security practices. You make yourself/users significantly more vulnerable with these suggestions for no gain.
