My mother had a strong aversion to Windows 8 but eventually upgraded to Windows 10 and later embraced Windows 11. Windows 11 will soon update its File Explorer to display file sizes in KB, MB, and GB instead of just KB. This change is expected to be welcomed by many users, although some may find the adjustment challenging. There is a discussion about user preferences regarding changes in familiar features and the potential for Microsoft to retain legacy options alongside new enhancements.

Microsoft reassured Windows 11 and Windows 10 users that their PCs will continue to boot normally and receive updates even if they have not yet received the new Secure Boot 2023 certificates. The rollout of these certificates is expected to continue over the upcoming months. The initial Secure Boot certificate expired on June 24, 2026, and Microsoft has been replacing older 2011 certificates since 2024. The latest update, KB5101650, transitioned Windows 11 to OS builds 26200.8875 and 26100.8875 for versions 25H2 and 24H2, respectively. The 2023 certificates replace older certificates with modern cryptographic standards, allowing Microsoft to deliver DBX revocation updates without interruption. Devices using the 2011 KEK can only receive DBX updates signed with that key, which is no longer valid after June 24. Microsoft has been rolling out the 2023 certificates for the past two years, and many devices remained in a yellow or red status by the June deadline. To check Secure Boot status, users can navigate to Windows Security > Device Security. A green checkmark indicates successful application of the certificates, while yellow and red alerts indicate compatibility issues or firmware incompatibility. PCs that are older or operating in Legacy BIOS mode will not receive the updates. Windows 10 also receives Secure Boot updates, but enrollment in Extended Security Updates (ESU) is required.

Microsoft has halted the deployment of its latest Patch Tuesday update for Windows 11 on select Dell PCs due to incompatibility with Intel's IPF driver, which caused issues such as unexpected shutdowns, overheating, and decreased system performance. Microsoft is working to resolve these complications and has released an emergency out-of-band update, KB5121767, for Windows 11 versions 24H2 and 25H2 to address the concerns.

Users may experience double reboots when installing substantial Windows updates, such as the April and July 2026 Updates, due to factors like Secure Boot and .NET Framework updates. The July 2026 .NET Framework update specifically requires a separate reboot. Microsoft is still rolling out the Secure Boot 2023 certificate update, which may also lead to multiple reboots. Users are advised not to panic during these reboots and to allow the system time to complete the installation process. Additionally, Microsoft has warned against delaying updates for more than three days due to increasing update sizes related to security vulnerabilities. Some users may encounter SCEP certificate errors in the Event Viewer after the July 2026 Update, but these errors do not indicate a failure of the update process.
