Admittedly, the catalog is horribly indexed. I was directed to the catalog from the link I posted (I applied the rollup at work and they disable windows update). Their brilliant fix, after I did the legwork, was to tell me to install the rollup. Since I couldn't find it in Windows Update, I went to the provided catalog link.
It showed 4 items (when I clicked on the link for Windows 7). 2 for Win7, 2 for Windows server 2008 as I recall. At the time, each of the two had the same description. I opened both Win7, and one was x86, the other, while it mentioned 64 bit or x64 (I forget), the X64 had AMD in the name. I think the description said it was for 64 bit systems. They have since updated it and the names say C86 and X64. In any case, updating manually from the catalog worked. Since I was told to do that at work, I did it.
I'm reluctant to apply it to my home PCs, and was really hoping to get some input here. Soon I'm going to give up and apply the rollup, which basically is defeating the two main reasons I didn't get Win10, buying a system with a built-in death. (I have enough stuff on my PC, including a PCIe NVMe drive requiring a slew of drivers to even come up, so if I get it wrong I'm in trouble, so I'd be nervous to downgrade to Win10... plus it might not be free by then.) I didn't want the blind updates, and I didn't want the telemetry. Well they've added the telemetry to WIN7 which I will on doubt be subject to when I install the rollup. And for the blind updates (take all or get lost), well I guess I now have to voluntarily do that.
I was hoping for some activity here -- the people who posted about how to disable the telemetry, any news of microsoft releasing just a fix for what they broke instead of forcing "everything INCLUDING the kitchen sink" on us if we simply want to fix what they broke. So far, nothing. As I have been saying, if they WANTED to force this on us, it was a brilliant move. Kinda hard to think that a security update accidentally broke indexing, and just outlook indexing at that.
