Note An Exchange Server software update is an executable (.exe) file that contains one or more system files that you can apply to Exchange Server to correct a specific problem. Software updates are distributed by Microsoft Product Support Services (PSS) to customers who are severely affected by a specific problem. Critical and recommended software updates are software updates that Microsoft recommends for all customers. Critical or recommended software updates can be obtained from the Windows Update site, the Microsoft Download Center, or from other Microsoft Web sites.
Microsoft has adopted this new naming schema for software update packages for the following reasons:
- It creates consistency across Microsoft software update packages.
- It improves the ability to search for software update packages and Microsoft Knowledge Base articles.
- It clearly notes the language of a software update package and the intended operating system when applicable.
