It's primarily a "quality" improvement update and as such, unless you click on the "check for updates" button, it won't be released to most users. It was released about a week ago and I'm guessing the "fixes" in this update will be included in the July 2019 "patch Tuesday" cumulative update when it's released in about a week. Read the Microsoft article about it below:

was ".175" Windows 10. Just decided to check 'updates' before I went to visit family for 4th. Don't know when it became available. Looked for update and security forum but didn't see it, the 'forum' that is!
