now i can't turn on my bluetooth anymore.
The slide button doesn't show up in my settings. what can i do about it? I think that the last number of the update was .3, but i already had .4 installed (I saw this too late).
Well, your question answers my question. You do not have a NUC, which is what this forum is for.
What is the model number of your laptop or desktop?
What version of Windows 10? 1909?
Why are you not using the driver provided by your laptop or desktop manufacturer?
What indicated the driver on this site as being the most relevant?
