81-Toggle-Scale.ps1 writes LogPixels, Win8DpiScaling and AppliedDPI for the current user; the change needs a restart, so the .bat launcher offers to restart at the end. It is picked up by the existing NN-*.bat/.ps1 globs and copied to Desktop\Tools. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
