Windows 11 Reliability Backlash and KB5074105 Preview Update Fixes

Microsoft reported over 1 billion monthly active Windows 11 users, but user sentiment remains negative, with prominent complaints focused on buggy updates, perceived reliability regressions, and unwanted feature changes (including AI-related additions). Microsoft leadership publicly acknowledged the feedback and said the company will prioritize performance, reliability, and overall user experience improvements to rebuild trust.

Microsoft also released the KB5074105 optional non-security preview cumulative update for Windows 11 (24H2/25H2), positioned as an end-of-month quality update ahead of the next Patch Tuesday. KB5074105 includes dozens of changes and targets operational issues including boot problems (e.g., startup hangs when Windows Boot Manager debugging is enabled and iSCSI boot failures with Inaccessible Boot Device), sign-in issues (including Explorer.exe hanging on first login under certain startup-app configurations), and activation/license migration failures during upgrades when devices cannot register with the Windows Activation server; the update is available via Windows Update or manual download from the Microsoft Update Catalog.
