Although Microsoft has repeatedly stated that the first service pack of Windows 7/Server 2008 R2 is just a collection of past update patches, it is undeniable that it will indeed bring some functional changes, but they will be less conspicuous. Last week, Windows 7 SP1 Build 7601.16556 v.172 was leaked. Users who like to try new things still can't feel any difference after installation, but the documentation that comes with it has been updated, from which we can get a glimpse of some new things in the service pack.
However, it should be pointed out that: First, the document "Significant changes in Windows 7 and Windows Server 2008 R2 SP1" was last updated in March. The things described in it are limited to the current test version and may not be the same as the final official version. There are differences; secondly, like Windows Vista/Server 2008 SP2, Windows 7/Server 2008 R2 SP1 is also the same service pack common on client and server operating systems. This is part of Microsoft's simplified service pack release strategy. measures.
Common changes for Windows 7/Server 2008 R2 SP1:
1. Improve energy efficiency:
Provides a user-mode based timestamp counter (TSC), which when used in programs such as SQL Server, provides a high-resolution multimedia timer (a necessary feature for OLTP, data warehouse processing, etc.), energy efficiency Much higher than previous plans.
2. Change the behavior of the "Restore previous folder window when logging in" function:
Located in the Folder and Search Options dialog box under the Organization menu in Windows Explorer. Before SP1, the previous folder window was restored based on the location of the most recently active folder. SP1 changed to the original location of all folders themselves.
3. Enhanced support for more identity authentication in RRAS/IPsec:
Add more identity types to the identity area of the IKEv2 authentication protocol, and use more types of identities when performing IKEv2 protocol authentication, such as E-mail ID and Certificate Subject.
Windows 7 SP1 specific changes:
1. Support efficient communication of third-party joint services:
That is, those that support the WS-Federation passive configuration protocol, thereby enhancing platform collaboration and improving identity and authorization information authentication capabilities between different organizations.
2. Improve HDMI audio device performance:
Some users reported that the connection between Windows 7 PC and HDMI audio devices will disappear after the system restarts. SP1 has improved this to ensure that the connection between the two is no longer interrupted.
3. Correct the behavior when printing mixed orientation XPS documents:
Some users have reported difficulties when using XPS Viewer to print XPS documents that contain both horizontal and vertical orientations, causing the entire page to become either all landscape or all portrait in a single mode. SP1 has solved this problem.
Windows Server 2008 R2 SP1 specific changes:
1. Dynamic Memory:
Limiting physical memory locations is the biggest challenge enterprises face when deploying new virtualization technologies and consolidating infrastructure. Dynamic memory is an enhancement of Hyper-V that allows enterprises to utilize physical memory and virtualization resources most efficiently. Dynamic memory allows memory on the host to be dynamically allocated to virtual machines on demand, increasing or decreasing dynamically based on the current workload without manual intervention.
Client systems supported by dynamic memory include Windows Server 2003 SP2 Datacenter Edition/Enterprise Edition, Windows Server 2008 SP1 Datacenter Edition/Enterprise Edition, Windows Server 2008 R2 Datacenter Edition/Enterprise Edition, Windows Vista SP2 Enterprise Edition/Ultimate Edition, Windows 7 Enterprise Edition/Ultimate Edition.
2. RemoteFX:
It can provide rich media user experience for virtual desktops, session-based desktops and remote applications, make full use of virtualized graphics resources, and provide localization for graphics-sensitive applications and various peripheral devices on various types of thick/thin clients. experience and improve the office efficiency of remote users.
RemoteFX operates independently of a specific graphics stack and supports any screen content, including Silverlight, Flash, and more.
RemoteFX also adds support for mainstream USB devices in virtual desktop computing, including USB flash drives, cameras, PDAs, etc., and provides a platform for software and hardware manufacturers to enhance RemoteFX in various hosts, clients, and network configurations. ability.
3. Enhance the flexibility and usability when using DirectAccess:
Supports 6to4 and ISATAP addresses when using DirectAccess with Network Load Balancing (NLB).
4. Support Managed Service Accounts (MSA) in a secure office environment:
Can be used for domain member services in network boundaries (DMZ/extension networks).
5. Support high-traffic authentication communication on domain controllers connected to high-latency networks:
As a large number of IT companies move to cloud-based services, authentication communication with domain controllers on high-latency networks (such as the Internet) has gradually become a bottleneck. SP1 can more accurately control the maximum number of concurrent connections of a domain controller, enabling more detailed performance adjustment for service providers.
