(misread) does your kb have drivers (from hp)? try loading latest of those maybe? or does it still get overwritten after regularly because ms for whatever reason thinks it doesn't have proper drivers and dump their load in?
Yes, the keyboard has HP drivers and it worked without issue until MS stuck its unwelcome nose in.
Thing is, the keyboard worked well for several weeks because I was able the prevent the regular 'update' and hide it. However, this latest 'update' was delivered via Scheduled Maintenance, which cannot be hidden or intercepted because it is delivered silently. This time, though, I don't think it is Microsoft drivers or the Mouse and Keyboard Centre.
I uninstalled all that and still no go with the keyboard.. I also tried another Bluetooth keyboard I have and it won't work, either. I therefore suspect MS has delivered its own version of Bluetooth drivers, and this is what is causing things not to work. Even transferring files via Bluetoth is now non-functional, so MS has messed thing up yet AGAIN.
I don't have troubles with the Logitich mouse, that's working just fine. My problem is with the Bluetooth keyboard that came with my HP 2-in-one. I had the issue before but was able to find, uninstall and hide the update that disabled it. However, the most recent update was delivered via Scheduled Maintenance and I had no way of intercepting it, and even though I uninstalled the Microsoft Keyboard and Mouse Centre and drivers that I didn't even need, being the previous culprit, my HP keyboard is still buggered.
I may have to go in and do a system restore to before the most recent round of updates to get the keyboard working again, then reload the updates one at a time until I discover which one's still preventing it from operating. Still, this is not something I should have to do. I don't have any Microsoft hardware connected to the 2-in-1, meaning I don't need the drivers or firmware, yet I've had to uninstall them/it 4 times now after 'update' buggered things up.
Starkers, don't you understand that MS knows much better than you do what you need and what is good for you. You just need to stop resisting and life will be so much more simpler for you. 
Yes, in its 'wisdom' [if such a term can be used when speaking of Microsoft], MS has decided a one-size-fits-all policy is best.... and whether you need it or not it's a case of 'open wide cos we're gonna ram t down your throat, like it or not'.
As I recall, a one-size-fits-all didn't work too well in the footwear industry, and the fashion industry gave it up as a bad joke, so why does MS think it has the answers for everyone's PC. Not everyone uses MS hardware, so why does MS see fit to deliver drivers for non-existent hardware.? Also, when users already have Nvidia, AMD and other drivers installed for the relevant hardware, why does MS still insist in delivering its own, inferior versions? And does Microsoft really have partners? Or are they subservient companies doing MS's bidding?
I recall the debacle when MS announced that Intel's new Skylake processors would not work with OSes prior to Win 10... in its bid to fob more versions of the OS onto more unwilling customers. Thankfully, Intel saw sense and realised that it would shrink the available market, so vehemently opposed the move.
Sometimes, corporations become to big and powerful for the good of the buying public, and when there is little or no viable opposition, as in the case of OSes, they have a captive market... which all too often they treat as they wish, with little or no regard.
Sadly, Microsoft has become one of those 'bugger the consumer' companies and has embarked on a trajectory of 'we know what's best for everyone... and they're going to get it, come hell or high water'.
There was a time when I felt Apple was the worse computer tech company on the planet, with its walled garden and user control policies, but Microsoft has rapidly caught up and will soon surpass Apple as being the worst PC tech company on the planet. MS might capture the imaginations and accounts of the yuppy set and trendy geeks, but its plans for its own walled garden and an OS subscription model will alienate older users and more. And for those who don't believe MS will go to subscription models, what do you think the Office 360 experiment was all about? It was testing the waters, plain and simple! Sadly, trendies and the yuppy set helped make 360 a success, therefore paving the way to subscription OSes.... Windows 10 up for rent.
The world is moving in some alarming directions: corporations bullying customers; Russia again flexing its political and military muscle; Trump behaving as badly and worse; the Middle East again becoming the melting pot for worldwide conflict, and Microsoft behaving like past dictators. Though dying isn't something I consider as being an answer to anything, when I look at the state of the world as compared to when I was a lad, I'm glad my time on the planet is drawing to a close rather than just beginning.
Were I a young newlywed in this day and age, there's no way on Earth I'd contemplate having kids, given everything is going to hell in a hand-basket faster than greased lightning buttered on both sides. It's great having grandkids, but I do worry about them, given the way the world in general is going, and how they will be affected by those who only think they know best.... and yes, Microsoft HAS contributed to that uncertain world. it may have been inadvertent, but Microsoft's clamour for power in the tech world has also changed things for the worst.
