  1. RemoveWindowsAI

    Force Remove Copilot, Recall and More in Windows 11

    Project mention: Get your Windows license refund | news.ycombinator.com | 2026-08-28

    The issue is the update license is different than full install licenses, and the red sticker oem licenses people scam are hardware specific.

    You usually must pay for windows twice (or more if you don't know) to be Pro license compliant for commercial use.

    Setting a machine up for multi-boot Linux/BSD is not always a simple process with every BIOS firmware, and configuring Windows to stop automatic encryption of NTFS volumes is nontrivial. Even with an offline install for games, if the OneDrive account is ever activated... files are upped to Microsoft cloud anyway.

    Thankfully, disarming Win11 TPM/Drive-boobytrap/BS-encryption/Spam is easy with Rufus, O&O ShutUp10, and Copilot removal (note undocumented AI API areas suggested RAT/snitch-ware... the final straw with Microsoft BS around here...)

    https://www.oo-software.com/en/shutup10

    https://github.com/zoicware/RemoveWindowsAI

    Yes it still supports DRM Steam games, and Win11 x4 gen4 SSDs are now about 17% faster i/o on my rig.

    You know what I like about Apple OS, is you just flip around 8 options and it goes quiet.

    Best of luck, ymmv =3
