How to get latest Intel Wireless BlueTooth driver

In device manager the yellow triangle shows as problem with Intel Wireless Blue Tooth.
I am running Windows 10 release 21h1 19043.1023.
HP Pavilion TouchSmart 23 all-in-one that is about 4 years old. I installed a WaveLink usb bluetooth dongle and I am trying get it connected to Sony headset to listen to audio books.
at one time I was getting a code csr8510 a10. this got you into a scenario where you had to download a zip file and then easydriver ? would try to sell you zip/unzip software to complete the job.
any ideas would really be appreciated.

I did run the assistant and it came back that all was up to date. also there was an update to DCH? and I am on another machine as the display updated and can't use the keyboard.
Now the error about the wireless BT has gone away but another one now appeared Generic Blue Tooth Radio. and when I searched the PC for updates to the driver it started and then failed due to corrupt file.
I also have a Asus BT 400 and I may try it.
Asus only had the error about Wireless BT where Wavelink had the generic BT radio.

So I guess I will try some things with what you and Brink sent me and see what happens. I delete the dongle from blue tooth devices when I try installing from the link Brink provided.

Good morning Denis
Re installed Windows 10. Completed all updates.
Then I installed the driver and support assistant. all went well. got a list of three items to install. selected install all. the first one dealt wifi and did not complete. two completed. then went back and tried re install on the first. all completed.
still a problem. did a search using windows update. found one Broadcom for Asus and installed it and in the list of blue tooth devices the dongle shows no errors but device manager shows now it is the wireless blue tooth driver is bad.
when I did a driver update I selected to search of the pc and found two files. i chose the one with the latest date and it installed.

Denis I have marked this solved. Asus is not my favorite co.
the assistant works great and even when I deleted intel it came back and flagged it again to re install.
I have kept all the instructions from you and Brink.
