DirectX 9 and Windows 10 question

Since updating to Windows 10, I've had DirectX 9 initialization error messages pop up in the background while running TS2016. The sim doesn't crash, but it does seem to pause briefly while the DirectX error message appears on screen. Clicking makes the error message go away and then Alt-Tab returns me to TS, so I've been ignoring this glitch. Today, I finally became curious enough to search for DirectX in "programs and features": not there. The next logical step seemed to be installing DirectX 9, which I did by running its setup within the Steam folder.
Now, I'm wondering whether this was a good idea or not . . . I'll reboot and see what happens. With fingers crossed, of course.
