Any new release of software will have some issues with some systems, no two windows systems are exactly the same, even in situations where systems are built and set-up to be identical, for example in controlled setups in business etc where standardisation is there to keep maintenance and replacement of hardware simple.
The fact that an internal component has a slight variance from standard that is within tolerance can cause the software to not work as specified. out in the wider world where we all decide to put a specific graphics card on a specific motherboard into our systems, and then often decide to push the boundaries by overclocking etc - It's amazing that many more occurences of first of early adopters seeing issues are not seen,
Yes there will be repeatable errors and issues in specific designs of PC/Laptop Hardware and this needs to be addressed urgently, but generic statements that an OS is bad because it does not work on a specific system 100% error free, is unjustified. Major Windows PC users, industries and enterprise level customers will never be first or early adopters, they will purchase a number of copies of software and test them to destruction, on test systems with their hardware setup and software load. They when they are happy with reliability then consider updates .
In a modern home with a eclectic mix of old and new , basic or advanced systems an issue on any one system is a problem for that user but will likely be fixed in short order if the issue is widespread and people follow good practice and report the fault back to the developer
