What is hot patching, and how does it benefit Windows Server 2025 users?

Hotpatching is a feature in Windows Server 2025 that allows administrators to apply security updates and patches without requiring a system reboot. This minimizes downtime and ensures continuous operation. Here are some key benefits of hotpatching:

• Minimal Downtime: Servers remain operational as no restarts are necessary, which is crucial for maintaining business continuity.
• Improved Security: Security updates can be applied immediately without waiting for maintenance windows, reducing the time systems are exposed to vulnerabilities.
• Reduced Resource Usage: Hotpatch updates are smaller and consume fewer CPU and storage resources, making them quicker to install.
• Simplified Maintenance: It simplifies the planning and execution of maintenance tasks, as fewer reboots are required throughout the year.
• Better Protection: Hotpatching patches the in-memory code of running processes, ensuring that updates are applied efficiently and securely.
