  I installed the Beta of SP1 on all of my Hyper-V servers a few months ago and will be upgrading to the RC once I have some time (probably this weekend).  The Beta was very stable, I expect the RC to be pretty much ready to go.  We are planning to release the RTM version of SP1 in the next few months…


Here are the bits:

The FAQ for SP1 is here, but I’ve detailed some of the high points below:

For Windows 7, Service Pack 1 is primarily the combination of previous released updates that have been delivered via Windows Update.  These updates are now combined into one easy to deploy package. 

For Windows Server 2008 R2, here’s the low down:

  • Dynamic Memory for Hyper-V
  • RemoteFX for remote sessions.
  • Plus the previously released updates for Windows Server 2008 R2.

Here’s some detail on the two new additions for Windows Server 2008 R2 SP1:

Dynamic Memory - allows your virtual machines to make more efficient use of memory.  Dynamic Memory allows Hyper-V to take memory from virtual machines that do not need as much memory and reallocate that memory to other virtual machines that can benefit from additional memory, real time.  Dynamic Memory can help with the workload changes and demands throughout the day / weeks of your virtual machine demands.  Dynamic Memory is very customizable so that you can ensure your more important workloads always have the resources they need. 

RemoteFX – This improves the desktop experience for users of Remote Desktop Services.  Traditionally, RDS users always had a reduced user experience compared to a local desktop user.  Now with RemoteFX, RDS users can achieve the a much richer desktop experience.  Keep in mind that this capability requires high end graphics cards on your Hyper-V server to make this happen.  We are building a list of the video requirements for this capability and I’ll talk about that in another blog entry soon…

If you installed the Beta of SP1, you must uninstall it before you can install the RC.  The Beta shows up in the Programs and Features list so you just choose uninstall and it will uninstall SP1, then reboot your server.  Once the uninstall is complete, you can now install the SP1 RC.

For now, check out the new RC and let me know what you think.

Until next time,
