About this tag

Discussions include troubleshooting sustained high GPU usage while the desktop is idle, which can cause stutter, heat, fan noise, slow window movement, screen flashes, or battery drain. The tag also documents multiple Microsoft security updates addressing vulnerabilities in the Desktop Window Manager, including elevation-of-privilege flaws and information disclosure issues, such as CVE-2026-65786, CVE-2026-62703, CVE-2026-61932, CVE-2026-50692, CVE-2026-50300, CVE-2026-45637, and CVE-2026-34336. These threads emphasize the importance of deploying cumulative updates through standard channels and understanding the role of DWM in Windows security.
