Question 1

What is the difference between the early versions of Windows and the modern NT kernel?

Accepted Answer

The early versions of Windows, from 1.0 through the 3.x era, were not full operating systems but rather graphical "shells" that sat on top of MS-DOS, requiring text commands to launch. This changed in 1993 with the birth of the NT (New Technology) kernel, which was built from scratch to be an enterprise-grade, stable, and secure foundation. While consumer versions like Windows 95 and 98 remained hybrid-DOS systems, the launch of Windows XP in 2001 finally merged the consumer and professional lines onto the solid NT architecture used today.

Question 2

What are the specific hardware requirements for the new "Copilot+ PC" designation?

Accepted Answer

To meet the "Copilot+ PC" standard, a computer must feature a specialized Neural Processing Unit (NPU) capable of at least 40 TOPS, which stands for 40 trillion operations per second. This specialized silicon is designed to handle AI tasks locally on the device rather than relying on the cloud, which improves privacy, reduces latency, and preserves battery life. Additionally, modern Windows 11 standards generally require a 64-bit processor and a TPM 2.0 security chip for hardware-level encryption and security.

Question 3

What does it mean for Windows to become an "agentic" operating system?

Accepted Answer

An "agentic" operating system shifts the user experience from a "conductor" model, where the user performs every step manually, to an "outcome" model, where the OS acts as an active participant. Using Large Language Models and "Agent Connectors," the system can understand intent and perform complex workflows across different apps, such as finding specific data in a spreadsheet or drafting a report based on emails. To ensure security, these actions take place in a "sandboxed" Agent Workspace with minimal privileges and a transparent audit log.

Question 4

What is "Hotpatching" and how does it improve the Windows update experience?

Accepted Answer

Hotpatching is a feature designed primarily for enterprise environments that allows security updates to be applied to the OS kernel without requiring a computer reboot. This technology aims to reach high compliance levels for security patches without interrupting the user's workflow with restart warnings. It works alongside "Virtualization-Based Security" (VBS), which isolates core parts of the operating system in a mini-virtual machine to protect the kernel from potential malware.

Question 5

When is the official end-of-support date for Windows 10?

Accepted Answer

Microsoft has set October 14, 2025, as the final date for free security updates for Windows 10. After this deadline, users must either upgrade to Windows 11, pay for Extended Security Updates, or continue running the operating system at a higher security risk. This deadline is a primary driver for the current transition toward newer "AI PCs" and the Windows 11 platform.
