Microsoft implements the first Inicialização Segura certificate replacement since 2011, a process that will require more frequent reboots on Windows computers. Current certificates expire in June, and the company has been rolling out the update gradually since April through regular security updates. The change mainly affects users with older machines and corporate environments with multiple monitors.
Certificados of Secure Boot expires in June with immediate impact
The new certificates function as digital security credentials that prevent malicious software from being loaded during device startup. Sem update before the deadline, computers will face problems verifying boot software in the future. Microsoft initially reported that a single restart would be required, but later clarified that the process would require multiple restarts.
Computadores purchased in the last two years have probably already received the automatic update. Older Máquinas present a different scenario: devices with Windows 10 may be left out of the process if they do not receive regular security updates. Essa deletion creates significant vulnerability on outdated systems.
Old Máquinas face pressure to migrate or invest extra
Outdated Dispositivos pose a special risk in this certificate transition.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 increases financial pressure on many users to upgrade hardware or migrate to Windows 11.
The gradual rollout of new certificates minimizes mass outages, but the volume of expected reboots remains a concern for enterprise environments. Organizações with old machine parks should evaluate in advance whether they will invest in ESU or hardware renewal before June.
Recent Atualizações causes display issues on multiple monitors
Updates KB5083769 and KB5082052, 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.
- Current Certificados expire in June 2026.
- Atualizações KB5083769 and KB5082052 caused display issues on multiple monitors.
- ESU offered as an alternative to Windows 10 without regular support.
- Solução for corrupt message in development by Microsoft.
Microsoft identified the problem and confirmed that it is working on a solution, but the fix has not yet been implemented. Usuários with multiple monitors should check the scales of each screen before applying future updates to avoid similar problems.
Renovação of certificates strengthens security against firmware malware
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. The change marks a pressure point for adopting newer versions of the operating system.
Usuários must ensure that their devices receive the automatic security updates enabled in the Windows Update settings. Microsoft continues to monitor reports of issues related to recent updates and expects implementation of the broken message fix in the coming weeks. Organizações and home users should prepare for expected reboots until certificates expire in June.
