Installed Win10 Fall Creators Update 1709 yesterday. Although I approached the task as would a wounded wilder-beast approach the lion's watering hole, it was a slow day so I figured "WTF."
After 40 minutes, and after final restart, searching my IMAP and mailboxes...FAILED. Failed as in didn't work. As in no results. And -- upon closer inspection -- I found that the Windows Indexing Service had...disappeared. Gone. As in didn't appear to exist any more. Wasn't present in services.msc.

A quick Google query revealed that, since September 2017, thousands of Windowssuckers users have experienced the same issue. Delving a little deeper it seemed everyone was pretty much clueless as to how to fix the problem. It took some time, but a posted suggestion that I reinstall Outlook resolved the issue (after a reindex of one-million messages which took hours)...but of course I mistakenly installed Outlook Professional Plus on top of my previous vanilla Outlook Professional installation (and in the process lost my Outlook product key whereby I had to burn another Pro Plus key).
