How To Add & Edit Email Accounts - Windows 8

The security landscape for Windows 8 and 10 users remains a top priority this month. Here are the 5 biggest updates from the March 10, 2026, Patch Tuesday:

Critical Office RCE Patches (CVE-2026-26110): Microsoft released urgent fixes for a Remote Code Execution vulnerability in Office. Attackers could execute code simply through the Outlook Preview Pane, making this a "zero-click" threat.
Firefox & Thunderbird ESR Extension: In a major relief for legacy users, Mozilla has officially extended security support for Firefox and Thunderbird ESR 115 until August 2026. This remains the most secure way to browse and email on Windows 8.
AI-Discovered Vulnerability (CVE-2026-21536): A critical Windows vulnerability discovered by an autonomous AI agent was fully mitigated this month, marking a new era of AI-to-AI security defense.
Secure Boot Certificate Deadline: Microsoft is pushing the final phase of Secure Boot certificate updates before the June 2026 expiration. Admins must apply these to ensure hardware remains bootable this summer.
SQL Server Zero-Day Fix: A publicly disclosed elevation of privilege flaw (CVE-2026-21262) was patched, preventing attackers from gaining "sysadmin" rights over networked environments.
