I can find absolutely nothing wrong in how Windows Update is behaving, but none of the machines at my house have received this update.
In reading through the documentation I can find it is not clear if this update was to undo some of what came out just a bit too quickly in response to Spectre and Meltdown and caused issues.
All of my machines, laptops with AMD A-series APUs, and a desktop running a vintage (at this point) Intel Pentium have all done many update checks since this thing went live on January 31st, but none seem to be getting it.
I do not want to install this thing from the catalog if it's not necessary since I'm having no issues with build 16299.192. I just want to make sure I'm not missing something somewhere. If this were being skipped on one of my machines I'd suspect a problem with Windows Update on that one, but on all of them, no.
