Microsoft has resolved lag and stuttering issues with NDI streaming software on Windows 10 and Windows 11 systems that occurred after the August 2025 security updates. Users reported severe performance problems, particularly with RUDP connections, linked to updates KB5063878 and KB5063709. Microsoft released updates KB5065426 and KB5065429 to fix these issues and recommended users install them. A temporary workaround involves changing the NDI Receive Mode to TCP or UDP. The September 2025 updates also addressed additional issues related to User Account Control prompts and app installation difficulties for non-admin users, as well as problems with security updates failing via WSUS and disruptions to Windows reset and recovery operations.
