Before starting a bare-metal installation of Windows 10, ensuring that there is sufficient storage space on the system's hard drive or SSD is crucial. This is because the installation files need enough room to be copied and for the operating system to be installed and function properly. Without adequate storage, the installation process can fail or the operating system might not perform optimally. Other prerequisites like internet connection, product key, and specific firmware types might be necessary at different stages of installation or activation, but the fundamental requirement is enough storage space to accommodate the new OS.

Resource Monitor is a Windows utility that can be used to monitor and analyze the system resources and processes running on a computer. It can be used to identify and troubleshoot any issues that might be causing the computer to run slowly, such as CPU usage, memory usage, disk I/O, and network usage.

When a legacy application is not fully functional after upgrading the Windows operating system, the first step to troubleshoot the issue is to:
* Run the application as Administrator: Legacy applications often require administrative privileges to run correctly. Running the application with these privileges can resolve issues related to permissions and access to certain system resources.
* Raise the User Account Control level: This increases security prompts but does not resolve compatibility issues.
* Turn off Windows Defender Firewall: This can expose the system to security risks and is unlikely to resolve application functionality issues.
* Disable compatibility mode for the application: Compatibility mode should generally be enabled for legacy applications to ensure they run properly on newer OS versions.

The best protection against physical threats, especially in a common area where the computer is publicly accessible, involves physically securing the hardware.
* Option A: Using screen lockScreen locks are good for securing access temporarily but do not protect against physical tampering or theft.
* Option B: Installing a privacy screenPrivacy screens prevent visual access but do not secure the hardware.
* Option C: Implementing password complexityPassword complexity helps secure digital access but does not prevent physical threats.
* Option D: Locking the computer casePhysically securing the case prevents unauthorized individuals from tampering with internal components or stealing the computer.
* Option E: Enabling drive encryptionEncryption protects data but does not prevent physical access to the hardware itself.
