Microsoft is rolling out to Fast Ring Insider testers a new Windows 10 19H1 test build. That build, No. 18267, includes a number of fixes and minor features, plus a new enhanced mode for search indexer.
The new search indexer mode will allow Windows to search all of a user's folders and drives, not just documents, pictures, video and desktop by default, according to Microsoft's October 24 blog post about the new build. To turn on the new search-indexing feature, users should go to teh Searching Windows Settings and under "Find My Files," select "Enhanced" in order to kick off the one-time indexing process.
Microsoft officials said the updated indexing process should take about 15 minutes to take effect, though it may be longer if users have a lot of files. Users also have the option to exclude a folder from search by adding it to the Excluded Folders list.

Microsoft is expected to begin rolling out Windows 10 19H1 to mainstream users around April 2019.
