Just a heads up for anyone who hasn't yet been offered this update.
From a cursory glance, it appears to only resolve a bug involving Bluetooth drivers. I'm yet to install it myself, but just posting this as news for those who are interested - specifically the Windows 7 remain camp. - Coldheart2236
Microsoft has surreptitiously replaced its old Windows 7 Update speed-up fix with a new version that still breaks Bluetooth, leaving many users bewildered -- and a few of us fuming.
This update rollup is superseded by July 2016 update rollup for Windows 7 SP1 and Windows Server 2008 R2 SP1 (KB3172605) that was released on July 21, 2016.
Unless my Windows Update scans start slowing down again, I think I'll wait until after the Windows 10 offer expires
I've just installed 3172605 using the stand-alone from the MS Download Center, with no noticeable issues following a reboot. As of now, I am being offered absolutely no further updates via the Windows Update client. As a side note, my update scan time was just over half a minute. - Coldheart2236
