Restart requirement

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. These include 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. 

Update removal information

To remove this update, use the Add or Remove Programs item in Control Panel.

Update replacement information

This security update does not replace a previously released security update.
The English (United States) version of this software update installs files that have the attributes that are listed in the following tables.
