I am **absolutely not** the person who downvoted your answer, but your answer doesn't answer a single one of the multiple questions the author actually asked.

Here is a list of the questions the author asked:

- Do all modern desktops not come with Bluetooth support?
- Is one generally expected to buy a Bluetooth adapter if they want Bluetooth on a desktop?
- Am I correct in concluding that it does not?
- Is there a way to use the steam controller's USB adapter as a Bluetooth adapter by any chance?

You indicate that Bluetooth modules are commonly associated with wireless adapters, which is common on laptops, but I fail to see how it answers any of the author's questions about their desktop.

The `PowerSpec G419` absolutely does not have a Bluetooth module.  If you had pointed this fact out, it's unlikely, your answer would have been downvoted.  You were also given feedback, granted it was under the question, due to the fact you deleting your answer.  That person indicated that due to the author's four different questions the question should be locked and improved before being answered.

In conclusion, you were so quick to answer the question you didn't even consider the possibility he question shouldn't even be answered in its current form.  I personally own a Steam Controller, which comes with an adapter, which will work flawlessly with the controller.  In other words, the Steam Controller comes with its own Bluetooth (USB) adapter.  Y**our answer fails to point out this fact, in your haste, you failed to identify the real question the author had.**

To be clear the author simply wanted to know how to get their Steam Controller to work.
