Lost control of Folio 9470m keyboard, sound, mouse

[sprstock]

My HP Folio 9470 laptop running Windows 10 Pro (64 bit) is now disabled after it loaded a Microsoft Windows 10 monthly update.  It is running an Intel i5 (3427U 1.8 GHz CPU, 16 GB RAM, and a Samsung 850 EVO 500GB SSD.

It would do as described below occasionally before the update but it is constant now.  Initially the calculator would pop up showing 0 or 47 repeatedly, continuing to open 6 or more calculators.  They would be running at the same time all displaying the same thing.  When I tried typing into a search engine, "asd,47kl=[" (without quotes) would show in the search field.  When this happened I would be unable to enter, clear or delete anything for a period of time, then without reason or cause it would quit showing that and I would be able to use the laptop as normal; and then again for some unknown reason it would start showing the calculator again with 0 or 47 and the asd,47kl=[ again in any field that would take other than numeric figures, such as an email you were typing, a search field, document or spreadsheet.

Initially I would start normally, then the computer would shortly degrade into showing the calculator, in multiple openings or instances.  When I start Word, I was at first able to type but not the letters a, s, d, (if any of the other symbols in the recurring text string were not typeable, I don't know).  It has now degraded to where it will type nothing at all.  I notice I have no control over the speaker or sound.  I cannot quit or turn the computer off.  I have Googled these problems and find I am not the only person who has run into this same thing, including the letter or symbol string being identical.  Common opinion seems to think they are driver problems, but whatever it is seems to have been triggered into being a constant occurance by the update.  The consensus is HP has not issued a driver fix for the problem nor have they addressed this problem even though it seems to be somewhat common.

Rebooting has done no good, cold rebooting seems to reset things temporarily.

Before the cold boot, I was trying to move some icons on my desktop.  Instead of moving them it would make copies of them.  After the cold boot I was able to move them until the calculator came up again and after closing the calculator, it started making copies again.  It would seem that in addition to losing control of my keyboard it has triggering some kind of mouse or selection problem as well.,

The Device Manager is showing one problem device (and has been for over a year now since upgrading from Windows 7 Pro to Windows 10 Pro) that is described under "Other Devices" and then subheaded under Base System Device, which was searched an IT guy and found to be a for a card that was described as a quick start card that held all of the credentials.  The next subheaded item only has a question mark and is described as Sdlproxy and the next one is also a question mark with a description of SMS/MMS Message Access.

Can anyone help me get my laptop working again?

Thanks.
