This PowerShell script performs the following steps:

• Includes a hashtable $licenseStatusDescriptions that maps each `LicenseStatus` value to its corresponding description. When adding the results to the array, it uses this mapping to convert the numeric `LicenseStatus` to a descriptive string.
• Queries all domain computers with an operating system that includes “Windows Server”.
• For each server, it retrieves the license status using the Get-CimInstance cmdlet.
• Collects the results into an array.
• Exports the results to a CSV file located at C:\temp\WindowsServerLicenseStatus.csv.
