The latest major update from Microsoft, identified as KB5083769 released in April, has led to various disruptions for Windows 11 users over recent weeks. These include instances where BitLocker activates unexpectedly, systems enter endless reboot cycles, and compatibility issues arise with external backup software. A fresh complication involves sudden black screen failures.
Reports from Borncity, via automated translation, highlight user reports of complete system halts and irregular, pixelated visuals. A shared online message details these experiences.
The problems seem concentrated on specific HP and Dell models, especially those equipped with NVIDIA GTX 1080 Ti graphics cards. Many individuals find themselves trapped in the Windows Automatic Repair mode.
Microsoft has yet to include this concern in their official roster of acknowledged problems. Recommended fixes involve utilizing System Restore, running Startup Repair, or opting for the 'Reset this PC' feature as a last resort.
A boot failure cycle was first documented on Microsoft community boards on April 17, 2026, directly linked to this update. The impacted system belonged to an owner of an HP Pavilion 590 p0044.
Additional accounts echo these troubles in the discussion, with one individual noting an incident from April 16: a previously stable setup crashed post-update, displaying a Blue Screen of Death with a kernel_security_check_failure error, and any reboot attempt recurs the same error.
On April 21, 2026, a further report emerged (translated from Greek): The system listed the 2026-04 Security Update (KB5083769) version 26200.8246 for installation two days prior. Following the restart after setup, screen distortions appeared, preventing access to Windows 11 Pro.
Despite multiple unsuccessful reboots, the automatic repair process eventually allowed normal startup. Yet, the update service repeatedly attempts reinstallation. The user suspended updates and employed the 'Show or hide updates' utility to block this particular patch. The procedure had to be repeated the next day.
Readers in the Borncity discussion area have corroborated these reports. It remains uncertain if these represent sporadic occurrences or a broader impact across users. Potential triggers for the Blue Screen errors include Dell SupportAssist software.
Microsoft has offered no official response regarding the situation. For those experiencing these effects, removing the KB5083769 update serves as the primary workaround. Further guidance on reverting recent Windows updates is available through standard resources.
Note: Windows 11 Home users may lack access to premium features available in Windows 11 Pro. For a detailed overview, consult comparisons between the Home and Pro editions. Upgrades are currently discounted in the PCWorld Software Store, priced at $59 rather than the usual $99.
