  • No More Excuses: Windows 7 Makes It Easy to Manage Computer Power
    • Products that earn the ENERGY STAR® prevent greenhouse gas emissions by meeting strict energy efficiency guidelines set by the U.S. Environmental Protection Agency and the U.S. Department of Energy. www.energy star.gov NO MORE EXCUSES: WINDOWS 7 MAKES IT EASY TO MANAGE COMPUTER POWER CONSUMPTION ORGANIZATION-WIDE Here’s how you can take advantage of Windows 7’s new power management features The University of Wisconsin at Oshkosh is no stranger to the idea of sustainability. In 2003 it became the first university in the state to join the Environmental Protection Agency’s Green Power Partnership. Its green initiatives also earned the university high marks from the Sierra Club, which ranked the university nationally in its Cool Schools survey. Given this commitment to green, it’s no surprise that the university first deployed computer power management back in 2005, and that it was one of the first Energy Star power management success stories. At that time, the University’s computers ran the Windows XP and Windows 2000 operating systems, neither of which included native tools for the central administration of power management features. To implement power management settings on these machines, the University used third-party software from ENERGY STAR called EZ GPO. For detailed information and resources concerning Now that Windows 7 has CPM client management features built in, it’s much the power management of easier to administer power management. This case study will show you how the University of Wisconsin at Oshkosh took full advantage of computer power PCs running Windows XP, management features on Windows Vista and Windows 7 clients managed by please see the ENERGY STAR Windows Server 2008.

  • Windows Server Update Services 3.0 SP2 Release Notes
    Windows Server Update Services 3.0 SP2 Release Notes These release notes describe the Windows Server Update Services 3.0 Service Pack 2 (WSUS 3.0 SP2) release. This document contains the following sections: 1. What‟s New in This Release 2. System Requirements for the WSUS 3.0 SP2 Server Installation 3. Configuration Prerequisites and Best Practice Recommendations for the WSUS Server 4. Windows Small Business Server Prerequisites 5. System Requirements for the WSUS 3.0 SP2 Remote Console Installation 6. System Requirements for Client Installation 7. Upgrade Requirements and Recommendations 8. Installing WSUS 3.0 SP2 9. Setup Command-line Parameters for Unattended WSUS 3.0 SP2 Installations 10. Known Issues What’s New In This Release Integration with Windows Server 2008 R2. Support for the BranchCache feature in Windows Server 2008 R2. Support for Windows 7 clients. Windows Update Agent (WUA) client improvements. The new WUA client offers a collection of performance enhancements, user experience improvements, plus an array of bug fixes based on customer feedback. Client scan time is faster than previous versions. Computers managed by WSUS servers can now run „scoped‟ scans against those same WSUS servers, instead of performing a full scan. This will result in order-of-magnitude faster scans for applications using Microsoft Update APIs such as Windows Defender. Windows Update Agent (WUA) user experience improvements help users better organize updates and provide greater clarity on update value and behavior. Imaged machines will be more clearly displayed in the WSUS console. For more information, see article titled A Windows 2000-based, Windows Server 2003-based, or Windows XP-based computer that was set up by using a Windows 2000, Windows Server 2003, or Windows XP image does not appear in the WSUS console.
