Windows Vista and Windows Server 2008 file information note- 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 | Milestone | Service branch  | 
| 6.0.6000.16xxx  | Windows  | RTM  | GDR  | 
| 6.0.6000.20xxx  | Windows  | RTM  | LDR  | 
| 6.0.6001.18xxx | Windows Vista SP1 and Windows Server 2008 SP1  | SP1  | GDR  | 
| 6.0.6001.22xxx | Windows Vista SP1 and Windows Server 2008 SP1  | SP1  | LDR  | 
 - Service Pack 1 is integrated into Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxxx version number. 
 - GDR service branches contain only fixes that are broadly released to address widespread, critical issues. LDR service branches contain hotfixes in addition to broadly released fixes. 
 - The .manifest files and the .mum files that are installed in each environment are listed separately in the "Additional file information for Windows Server 2008 and for Windows Vista" section. These files and their associated .cat (security catalog) files are critical to maintaining the state of the updated component. The .cat files are signed with a Microsoft digital signature. The attributes of these security files are not listed.
