Microsoft implements the first Inicialização Segura certificate rollover since 2011, a process that will result in frequent reboots of Windows computers until the current certificates expire in June. The company has rolled out the update gradually through regular security updates since April, affecting millions of users around the world. The new certificates are digital security credentials designed to prevent malicious software from being loaded during device startup.
Critical Cronograma and impact of reboots
Sem an update before the deadline, computers may experience problems verifying boot software in the future. Microsoft initially reported that a single reboot would be required during installation, but later clarified that the process could require multiple reboots. Esse scenario is of particular concern to corporate environments and home users with multiple monitors, where interruptions impact productivity and workflow.
Usuários who purchased computers in the last two years have probably already received the automatic update. Contudo, older machines face a different scenario: computers with Windows 10 may be left out of the process if they stop receiving regular security updates. The gradual rollout of new certificates seeks to minimize mass outages, but the volume of expected reboots remains a concern for various user segments.
Desafios on outdated machines and support options
Outdated Dispositivos present special risk in this transition. Para users with older PCs on Windows 10, Microsoft offers the paid ESU program (Atualizações from Segurança Estendidas), which provides security patches for an extended period of time. Essa option, however, increases the financial pressure on many users to upgrade to newer hardware or migrate to Windows 11. The change marks a pressure point for adoption of newer versions of the operating system, as older machines may lose access to critical updates without additional investment in extended support.
- Current Certificados expire in June 2026.
- Atualizações KB5083769 and KB5082052 caused display issues on multi-monitor systems.
- ESU offered as an alternative to Windows 10 without standard support.
- Solução for corrupt message in development by Microsoft.
Problemas recent security updates
Updates KB5083769 and KB5082052, recently released to fix security vulnerabilities, have caused adverse effects on some devices. Usuários reported corrupted error messages when opening Área files from Trabalho Remota, making critical information virtually unreadable on the screen. The defect occurs mainly on systems with more than one monitor configured with different scales. Microsoft identified the problem and confirmed that it is working on a solution, but the fix has not yet been implemented in public versions of the system.
Impacto on security and practical recommendations
Frequent Reinicializações represent trade-off between functionality and protection. Certificate replacement strengthens the security of Windows PCs by renewing credentials that verify software integrity during boot, reducing windows of opportunity for firmware-level malware attacks. Usuários must ensure that their devices receive the automatic security updates enabled in the Windows Update settings. Para those with multiple monitors, it is recommended to check the scales of each screen before applying future updates.
Organizações with old machine parks must evaluate in advance whether they will invest in ESU or hardware renewal. Microsoft continues to monitor reports of issues related to recent updates and expects implementation of the broken message fix in the coming weeks.
