All my profiles have degraded and now produce only badly faded prints. Some are from HP and some are my own using i1Studio and their hardware. All worked well about a year ago.   The only decent print I now get is using "Let printer manage colors" and the Adobe RGB.
Because this effect  happens in Qimage and Afinity and Lightroom I suspect Win 10 updates. Is this a known problem and what might fix it?
Many thanks for any guidance,

Hard to tell what to blame, but you obviously have a grasp of the situation.
Are we talking about camera profiles or printer profiles?
I suspect printer profiles.
Every so often there is a color management upgrade included in Qimage. If memory serves, it is a .dll file like LCMS.dll.
As you stated, Windows 10 updates have messed me up a good number of times too.So my guess, either your profiles are off due to color management upgrades, or they became corrupted during a W 10 update,but Adobe RGB is OK, sort of points to the profiles that you made.
All printers I know of now offer profiles free. Match the paper, and test it.
Hope some of this helps.

Thanks Fred. I may load Win 8 onto a spare computer and see what happens.

I dunno.. W 8.1 was sort of a greased ladder to W 10
Do you have a W7?   I would simply try a profile that comes free with the printer driver and match to the paper.

My printer is an HPT120 and HP advised that most Win 10 ,(and other ) problems can be fixed by installing the latest drivers. I have done this, which I previously avoided because the latest ones have been dumed down for simpletons. The result is that Qimage now locks up and only Task Manager (Windows) will get out of the lockup. Restarting the machine doesn't improve things. What might be causing this? Thanks again for an suggestions.

Fixed locking of Qimage by installing lates ;Dt firmware.
