Windows Hello is a biometric-based technology that enables Windows 10 users to authenticate secure access to their devices, apps, online services, and networks with just a look or a touch. If users have difficulty using the facial recognition feature, Windows Hello also supports a Personal Identification Number (PIN) as a secondary feature for logging in. The PIN is tied to the specific device on which it is set up, adding a layer of security even if the PIN is obtained by someone else.

Personal identification number: The PIN serves as an alternative to the facial recognition feature, allowing users to quickly and securely access their devices without relying solely on biometric authentication.

Username/password (B) is the traditional method of authentication but is not specifically a secondary feature of Windows Hello. One-time-use token (C) and cryptographic device (D) could be part of an MFA setup but are not directly related to Windows Hello's alternate authentication options.

When a WAP (Wireless Access Point) mesh network is experiencing a higher than anticipated amount of traffic, leading to degraded network service, upgrading the network to a more advanced wireless standard can help alleviate the problem. The 802.11n specification, also known as Wireless-N, offers significant improvements over earlier standards like 802.11b/g in terms of speed, range, and reliability. It allows for increased data throughput and better coverage, which can support a higher number of wireless users effectively.

Upgrading to 802.11n: This involves replacing existing WAPs with those that support the 802.11n standard or higher. The upgrade can result in improved network performance by accommodating more wireless connections with higher data rates, reducing congestion and improving overall network efficiency.

Replacing non-mobile users' laptops with wired desktop systems (A) could reduce wireless traffic but may not be feasible or desirable for all users. Increasing the wireless network adapter metric (B) would affect route priority but not overall network capacity. Adding wireless repeaters (C) can extend the range but might also introduce additional latency and does not necessarily increase the network's capacity to handle more users efficiently.

When encountering a warning about antivirus protection malfunctioning, the first step should be to isolate the computer from the network to prevent potential spread of malware. Updating the endpoint protection software is also crucial to ensure the latest virus definitions and security features are in place to effectively identify and remove the threat.

The most likely reason for an error message stating "Not compatible with OS" during a software installation is that the installation requires administrative rights. Many software installations, especially those that affect system files or install drivers, require administrative privileges to execute correctly. Without these rights, the installer cannot make the necessary changes to the system, leading to such error messages​​.
