Refactors ISO path handling for clarity and robustness

Browse Source 
Inverts the conditional logic for determining available Windows releases and versions based on whether an ISO path is provided.

This change improves code readability by checking for the positive case (an ISO is present) first. It also adds validation to ensure the file path ends with the `.iso` extension.
