Update Rollup 3 for Windows Home Server 2011 and Windows Storage Server R2 Essentials Released August 14 2012

Quietly, on August 14th 2012, just one day before Windows 8 RTM is expected to be available to Technet and MSDN subscribers, Microsoft released Update Rollup 3 for Windows Home Server 2011:

and Update Rollup 3 for Windows Storage Server 2008 R2 Essentials:
http://support.microsoft.com/kb/2705122

Considering it's 159MB of stuff, yes, the fix list is quite long. Read it, backup your server, then give Windows Update (through RDP or the Dashboard) a try, and reboot of course. Finally, it says you can now minimize LaunchPad upon start, so when your family member's system  is rebooted, they're not annoyed by that UI.

So, what's particularly interesting about the timing?

Well, if you're trying Windows 8 RTM later on today, this particular fix sure sounds helpful:

Assume that you connect a Windows 8-based client computer to a Windows Home Server 2011-based server, and then set the client backup property to "Automatically wake this computer up from sleep or hibernation to run a scheduled backup." In this situation, the backup is not successful if the client computer is asleep or in hibernation.

KB2608659 - Update to fix issues with Single Instance Storage (SIS) for 2008 R2 that may lose or corrupt data

Hmm, does that include the Home Server variants? Well, apparently not, but that's strange, isn't the SIS engine the same across variants?

Anyhow, the article clearly states:
