A couple of weeks ago I downloaded the Dell Wireless 1830 Update that has a Release Date of December 22nd, 2016 (although the "View Details" indicates that it was released on January 16th, 2017). Assuming that this was an update, I tried to apply this to my XPS 15 9550 but the update failed. The generated log really did not tell me much but when I investigated what driver version I currently have, I realized that I already had the v18.104.22.1680 driver installed with a driver date of 9/23/2015. It apparently was installed as part of the Anniversary Update last August. However looking at the Programs and Features list, the "WIDCOMM Bluetooth Software" entry shows the version of 22.214.171.1240 which was the original installation date back in December 2015. I suspect the Anniversary Update changed the driver without updating the underlying software indicator. Below is the pertinent part of the log. I would appreciate if Dell could comment on this.

The Windows 10 Anniversary Update was compiled by Microsoft, not Dell. We have no way of knowing what drivers they included or why.
When I go to the Dell XPS 15 9550 driver page for Windows 10, I do not see a Dell Wireless 1830 update dated 12/22/16.
I find the following =
Dell Wireless 1830 Bluetooth Application
Version 188.8.131.520, A01
Release date 10/14/15
Older versions =
There are some driver in the Network section. Why they would put Bluetooth drivers in two different sections, no sure.
When I bring up my Service Tag, I see an update "Dell Wireless 1550/1560/1704/1708/1820A/1830 Bluetooth Driver" with a file named "Network_Driver_YW21W_WN32_184.108.40.2060_A04_01.EXE", released Dec 22, 2016. This is in the "Network" section. It is indicated as applying to the XPS 15 9550 and was the one I attempted to apply to my system. I also see the update "Dell Wireless 1830 Bluetooth Application" (version 220.127.116.110) which is in the "Modem/Communications" section. This is the one originally installed on my system as shown in my "Programs and Features" list as "WIDCOMM Bluetooth Software". This is very confusing as Saltgrass indicates. I would think that these would be consistent and show the same version. It seems that the Anniversary Update updated the driver (provided by Broadcom) but the underlying "software" version indicated in "Programs and Features" was not changed. Microsoft directly updating drivers is causing havoc. There were a number of driver updates inclided in the Anniversary Update for which no indication was given.
