This hotfix does not require a system restart. However, it will trigger a restart of all Internet Information Services (IIS)-related services, including the IISADMIN, W3SVC, FTP, and SMTP services. This behavior occurs because the base product MSI file for the .NET Framework 2.0 includes instructions for restarting these services. Therefore, every update to the product will execute these instructions.
