firmware changes

Microsoft will begin the expiration of Secure Boot certificates on most PCs in June, marking the end of a 15-year period of stability. This affects all PCs manufactured before 2023. Users will likely need to perform multiple restarts during the update process, which includes pushing data into firmware and loading a new bootloader. Ignoring the Secure Boot deadline in June 2026 may lead to significant security risks, as Microsoft will stop providing essential boot updates and malware blacklists. The Windows Security App has been updated to help users monitor these changes, and users should check for warnings indicating the status of Secure Boot. It is important for Windows 10 users to ensure they are enrolled in the Extended Security Updates (ESU) program to avoid vulnerabilities.
