Windows 11 Beta Preview (26H1) Build 28020.2236 Patches Background Stalls and Quiet Stability Gaps
Windows Insiders in the beta track just received Build 28020.2236 for the 26H1 preview cycle. The quiet release focuses on background service throttling and memory leak patches that prevent the exact disk thrashing common in extended preview sessions. Microsoft quietly fixed explorer navigation timeouts and telemetry conflicts that previously forced hard reboots during routine file management. Testers should treat this flight as a stability foundation rather than a feature showcase and keep recovery media ready for any lingering preview quirks.
