A Windows 11 bug blocks all updates since February. Here's what to do

PCWorld reports a Windows 11 bug has blocked all updates since February for some users, creating serious security vulnerabilities and potential system issues. The problem stems from January's Preview Update and affects download timeouts, leaving systems without crucial monthly security patches and upcoming Secure Boot certificate updates. Microsoft recommends performing a Known-Issue Rollback (KIR) to revert the faulty update and restore normal update functionality. Problems with Windows updates are nothing new, but right now there's a seriously annoying bug that's affecting certain Windows 11 users--they haven't been getting any Windows updates for months. According to BleepingComputer, the issue started after installation of the January Preview Update. This means that those affected have not received a single Windows update since February, and that includes all the monthly security updates that should be keeping them safe. As if that weren't bad enough, we're also at a critical juncture just weeks before Secure Boot certificates expire on older Windows machines. Microsoft has been distributing updated certificates via Windows Update, which must be installed on PCs before June in order for Secure Boot to continue working as intended.
