The web installer is a small executable (typically a few megabytes) that acts as a downloader. Upon execution, it queries the Microsoft servers, determines the missing components required for the specific host operating system, and downloads only those binaries. While efficient for consumer bandwidth, it is a liability in enterprise deployment scenarios where internet access is restricted or reproducible, automated installations are required.
