Re: "Redmond is also attempting to block the devices trying the update again"
The main problem would be to identify the hardware which has the issue, and to do it without error.
Once it is done, it only needs to be added to the database which is used by the Win10 setup to check for compatibility issues when applying upgrades.
And for those who want to check their system compatibility before upgrading, once you have downloaded the full setup:
SETUP.EXE /Auto Upgrade /Quiet /NoReboot /Compat ScanOnly
Results will be available in C:\$Windows.~bt\Sources\Panther\ScanResult.xml, or in the *compat*.xml files in that same folder.
