Windows 7 file information note

Important Windows 7 and Windows Server 2008 R2 updates are included in the same packages.

• The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:
  

  Version	Product	SR_Level	Service branch
  6.1.760 1. 17xxx	Windows 7 and Windows Server 2008 R2	SP1	GDR
  6.1.760 1. 21xxx	Windows 7 and Windows Server 2008 R2	SP1	LDR

• GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
• The MANIFEST files (.manifest) that are installed for each environment are listed separately in the "Additional file information for Windows 7" section. MANIFEST files and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
