I am trying to alert Microsoft just now as I quite like having all my updates 'up-to-date'. Your description, including 'Thread stuck in device driver', matched my PC symptoms exactly and I have tried an awful lot of variations to solve it. This included completely dismembering the thing and disconnecting mousepad and keyboard, replaced by USB equivalent and even a close examination of the motherboard using a jewelers loupe. I even purchased some mini fans (5V) in the hope that it might just be a lack of cooling. It is now running with an SSD instead of HDD and although the operation is definitely not up to current speeds is more than enough for what I want as a portable travelling PC.
Currently the OEM no longer controls which drivers are used for their products on W10, the responsibility having been devolved to (taken by) Microsoft. When the OEM had control then at least they had a commercial interest for a while in maintaining their product.
