This update does not require a system restart after you apply it unless files being updated are locked or in use. However, installing this update will trigger a restart of all Internet Information Services (IIS)-related services, including the IISADMIN, W3SVC, FTP, and SMTP services. This behavior occurs because a base component for the .NET Framework includes instructions for restarting these services. Therefore, every update to the product will execute the same restarting instructions.
