February Windows 11 patch sparks boot loops and login failures for some users
A February Windows 11 update, KB5077181 (for 24H2 and 25H2), is causing critical startup problems for some users, including endless restart loops and login failures with error codes such as SENS, 0x800f0983, and 0x800f0991, as well as DHCP-related issues. Microsoft has not provided a fix or listed these problems as known issues. The recommended workaround is to uninstall KB5077181 via Control Panel and pause automatic updates to avoid reinstallation; some users have also tried recovery-mode resets with limited success. Users should wait for an official patch while safeguarding systems by delaying updates.
