Windows 10: Bluetooth Pairing Issue is with Format and appearance with the menu not the BT service itself

Hi, I've had this issue a couple of times now but it seems really silly and probably fingers crossed in hope an easy fix.When I try to pair my phone to send a txt file over BT for convenience the Windows 10 windows that pops up to confirm the pairing is short enough to cut off the code/"OK"/"Cancel" buttons and is non resizable. I have tried some key shortcuts to maximise and can't get that to work. I tried to TAB to the supposed "OK" option but no luck TBH though i'd rather get to the bottom of this because it's such an annoying issue with the windows UI, why did they make the UI different

Bluetooth hopelessly inoperable

Pardon,
I say hopelessly more as sign of my frustration than anything to do with hardware or configurations.

Let me explain: At one point it worked: All my attempts at pairing were successful, ie. Rift Sensors, external audio buds, peripherals mouse, keyboards, etc.

At some point, can't pinpoint, but months, a year, after above, was unable to pair anything from BT speaker to BT headphones, BT printer, etc.: The various set-up options within BT just repeatedly dotted across the screen. Should mention that all previously paired accessories remained listed and paired and functioning. Also the new peripherals easily paired with other BT equipped assets.

Here is what I tried: following a number of You Tube vids, I made sure drivers were fresh and up-to-date. At one point I accessed regedit to alter an entry suggested by a poster, changing 6.3 to C.2 (don't at moment recall specifics, anyway changed it back). Also by the same poster, fiddled with BT Services menu options which also were non-effective.

Now this morning realizing I have two (?) listings under Bluetooth in Device Manager (Dell Wireless 1706 Bluetooth and Microsoft Bluetooth Enumerator), I disabled one than the other thinking it may be a matter of conflict of interest, but, alas, none of what I attempted has had any effect.

I would deeply appreciate any ideas or suggestions which may jolt this misbehaving component into compliance. Thank you.

Windows 10 Bluetooth pairing issue

So, to keep it short: Suddenly my Windows 10 Bluetooth won't pair anything. I've tried multiple devices and every time I hit the "Pair" button, a minute goes by and I get an error:

or

Yeah, I'm trying to connect my PS4 DS4 controller to my Windows computer with Bluetooth. At first it worked like a charm, using the DS4Windows Software. The software installs an Virtual Bus Driver, which may be removed afterwards. That did not help me after my pairing problem occurred.

I suspect something is wrong with the Bluetooth Support Service, as it is this service responsible for the pairing part.

I've changed updated drivers, rolled back. Rolled back windows. Wiped drivers. Tried Generic Bluetooth drivers. Nothing.

Thing is, pairing worked a couple of days ago.

Any suggestions?
