This fell in my lap over the weekend, but I didn’t have time to cover it last week: An update is available that allows for a potential power saving in an AMD multicore processor that is running an x64-based version of Windows Vista SP2, of Windows Server 2008 SP2, of Windows 7, or of Windows Server 2008 R2.
The update in itself is worth a download and an install, to make post-Vista 64-bit platforms play nice with Enhanced C1 state (C1E) for lower power consumption for an AMD multicore processor. But what is interesting is that under Hotfix Support for Windows 7/Windows Server 2008 R2 it says SP1 (Service Pack 1) and SP3 for Vista.
Bink Says: This is a complete normal process, Windows 7 is RTM so any issues that are fixed after this will end up in the 1st Service Pack. It is normal that the KB on this issue mentions this. So a week after Win7 Sp1 is released a KB article might show up mentioning a hotfox that wll end up in Win7 SP2.
