General availability of Windows 7 & Windows Server 2008 R2, with IIS 7.5

As of today, Windows 7 and Windows Server 2008 R2 is generally available for purchase. This latest release of the Windows operating system contains IIS 7.5, which provides a set of enhancements and new functionality on top of the IIS 7 Web server platform.

Windows 7/Windows Server 2008 R2 also marks the first release of a Windows operating system release that includes Web extensions built and refined in our rapid innovation model. See the IIS Web Extension library for the new functionality which ranges from an application request load balancer/proxy to URL rewriting to a deployment platform for Web applications and server.

If you are an administrator looking for a simplified but powerful management experience, IIS 7.5 brings you:

  • built-in, brand new FTP server and WebDav support that we initially shipped as Web extensions, revised with customer feedback and added to IIS in the Windows operating system
  • new management console support for administering request filtering rules, FastCGI settings, and ASP.NET settings, part of an Administration Pack that we initially released as a Web download that also includes…
  • a rich IIS configuration editor built-into the management console to simplify configuration management and generate administration scripts for automated configuration management
  • integration with Windows Server 2008 R2’s new Best Practice Analyzer with IIS-specific best practice rules
  • a Windows PowerShell snap-in for IIS, with a library of task-based and lower-level commandlets for IIS administration – shipped first as a Web download and now incorporated into the IIS server in the operating system.
  • quality enhancements -- otherwise known as bug fixes :-) 
  • config tracing so you can audit changes to the IIS configuration system
  • application “pre-load” where you can decrease the response time for first requests to an application by pre-loading worker processes, using a Web extension called Application Warm-Up.

If you are a developer wanting to understand the implications of targeting an IIS 7.5 server, consider:

We hope you enjoy this release! We are hard at work now on adding new functionality to the IIS Web extension library for you to download onto Windows Server 2008 and Windows Server 2008 R2. Stay tuned for more free, fully supported downloads from the IIS server team that you can use to extend the functionality of IIS 7 and IIS 7.5.


  • Please be careful that acrobat reader is not compatible with IIS 7.5

  • To Lionel: Thanks for finding the incompat for IIS 7.5 and acrobat reader. We are working on a fix to the core operating system that will be released early next year. We will update with a link when it's available. Sorry for the inconvienence and thanks for the heads-up.

  • You state that .Net 4 is avaliable on core (first bullet point under the developers section). I haven't been able to find an installer that runs on Core R2. Can you help me out with that?
