  "textContent": "\n\n## Windows 11 KB5077181 Update Causes Boot Loops and System Stability Issues\n\nThe Windows 11 KB5077181 update creates boot loop problems which users need to understand as they require specific methods for solving these issues. The update KB5077181 which Microsoft released in February 2026 causes serious stability problems on Windows 11 systems that operate using the 24H2 and 25H2 versions. Users report that the update triggers endless reboots sometimes up to 15 consecutive cycles often resulting in a nonfunctional login screen or total system failure.\n\nThe update was meant to fix security vulnerabilities while it also provided new Secure Boot certificate updates for certificates that will expire in Summer 2026. The rollout has introduced several critical bugs which need to be addressed.\n\n  * **Boot Loops** The system undergoes repeated restarts which fail to reach the desktop environment.\n  * **Login Failures** System Event Notification Service SENS errors prevent users from logging in to the system.\n  * **Network Loss** The system experiences total internet disconnection through both WiFi and Ethernet due to DHCP failures.\n  * **Installation Errors** Update logs frequently show the presence of error codes 0x800f0983 and 0x800f0991.\n\n\n\nThe system allows partial operational use so users can start repairing system files through this method. Open Command Prompt as Administrator and run\n\n> sfc /scannow\n\nThe best method to fix the problem exists as a manual solution which requires users to uninstall the update that causes issues until Microsoft releases the official patch.\n\n### Method 1 Via Control Panel\n\n  1. Open Control Panel.\n  2. Go to Programs and Features.\n  3. Select View installed updates.\n  4. Locate KB5077181 and click Uninstall.\n\n\n\n### Method 2 Via Windows Recovery Environment WinRE\n\nYou need to access the Recovery Environment to remove the update through Command Prompt when Windows fails to start its login process.\n\nBoot into the Windows Recovery Environment (usually by interrupting the boot process three times or using a recovery drive).\n\nNavigate to Troubleshoot > Advanced Options > Command Prompt.\n\nType the following command and press Enter\n\n> wusa /uninstall /kb:5077181 /quiet /norestart\n\nThe computer needs to restart after the command finishes its execution. All connectivity problems and reboot loops should get fixed after this command removes the update.\n\nThe issues appear linked to changes in the Secure Boot mechanism. Users should stop Windows Updates until Microsoft provides a dependable solution for the 24H2 and 25H2 versions.",
