Re: KB3112148
If KB3112148 is for 64-bit Win7 machines, why has it been delivered to my 32-bit PC?
It's apparently beyond Microsoft's assembled wisdom to create a simple, two-layer (on top of its own Technet and other highly technical none-MS sources) explanatory system for Patch Tuesdays: one for a general audience that doesn't much care; and one for the far more technically inclined that supplies specific, detailed info about each upgrade.
Why do we need this? Because it has become abundantly clear, over the years since MS was heavily caned for using the WU channel to push inappropriate software to consumers, that this murkiness actually suits MS fine. It's working right now to pester the bejesus out of the unfortunates who installed the Win10 nags.
Other questions abound: why not include the relevant MSxxxx number with each use of the KBxxxx label, to improve our ability to research the KBs? Why do some KBs list as "critical" in the US, but only as "important" in Australia? And why, for pity's sake, is there any need to change the KBxxxx for the same update in different countries?
