What changes

Fixes 3 changes

Input

Gradual rollout

For: Insiders with the latest-updates toggle on

  • The mouse cursor no longer becomes invisible with a black box behind it when pointer trails are enabled. The cursor also moves without the unexpected stuttering described in the notes, and the ALT or Shift key no longer gets stuck down after a Windows Hello prompt.1

Graphics

Gradual rollout

For: Insiders with the latest-updates toggle on

  • Some games no longer appear oversaturated when Auto HDR is on.2

Rollback

For: Everyone in the Dev Channel

  • Rolling back from Build 26120.2510 to an earlier build no longer causes an incorrect app-blocking dialog when you use or install certain third-party apps.3
    The dialog said, “Your organization used App Control for Business to block this app”; it appeared because an incorrect policy was enforced.
