FILE INFORMATION

The English (United States) version of this software update installs files that have the attributes that are listed in the following tables. The dates and times for these files are listed in Coordinated Universal Time (UTC). The dates and times for these files on your local computer are displayed in your local time and with your current daylight saving time (DST) bias. Additionally, the dates and times may change when you perform certain operations on the files.

Windows Server 2008 file information

The files that apply to a specific product, milestone (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
6.0.6001.18xxx	Windows Server 2008 SP1	SP1	GDR
6.0.6001.22xxx	Windows Server 2008 SP1	SP1	LDR
6.0.6002.18xxx	Windows Server 2008 SP2	SP2	GDR
6.0.6002.22xxx	Windows Server 2008 SP2	SP2	LDR

Service Pack 1 is integrated into the release version of 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 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) and the MUM files (.mum) that are installed for each environment are listed separately. MUM and MANIFEST files, and the associated security catalog (.cat) files, are very important for maintaining the state of the updated component. The security catalog files (attributes not listed) are signed with a Microsoft digital signature.

For all supported x64-based versions of Windows Server 2008

Windows Server 2008 R2 file information

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
6.1.7600.16xxx	Windows Server 2008 R2	RTM	GDR
6.1.7600.20xxx	Windows Server 2008 R2	RTM	LDR
6.1.7600.17xxx	Windows Server 2008 R2	SP1	GDR
6.1.7600.21xxx	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) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are critical to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.

For all supported x64-based versions of Windows Server 2008 R2
