Today was the August security updates.
I still think SR1 was the update KB3081424 we got last week.
Microsoft fixes four critical security flaws in August's Patch Tuesday | ZDNet
So this is not the ballyhooed SR1 Update?
It could be.. hard to say though.
I got it BTW.. not an issue updating.
First cat out of the box after installing the 15 updates, I tried to start Edge and NO DICE! I get Message "Edge can't open while User Account Control is turned off. Start UAC.". Gee thanks, MS, I don't use UAC and have done just fine all these months without it. Looks like someone decided we now need to use UAC in order to use Edge whether we want to or not.
I did turn on UAC and then had to do a restart to register the change and Edge works just fine again. I will experiment further about whether I can turn it back off again.
After installing (KB3081436) my build string is 10240.16430........
