Windows blocks users from upgrading to 2004 and 20H2

We recently discovered that a bug in the 20H2 version of Windows 10 is affecting the use of NVMe SSDs connected through the Thunderbolt port and causing computers to display a blue error screen.

When connecting the storage device to the port, the system immediately returns the error “DRIVER_VERIFIER_DMA_VIOLATION (e6) An illegal DMA operation was attempted by a controlled driver”, accompanied by the terrifying OS error screen.

Now Microsoft has begun to implement a lock so that computers that may be affected by the outage cannot be upgraded to the two most recent versions of the software, 2004 and 20H2.

So if the user is still with Windows 10 in version 1909 or in an earlier version, he will not be able to update the system to the new versions.

However, the Redmond giant explained that this block is limited to computers with “affected drivers or firmware”, but did not specify what those drivers are. Still – as obvious as it may seem – the company explained that computers at risk of failure must have a Thunderbolt 3 port.

While Microsoft has not specified exactly what devices are involved, it is possible that all devices – or part of them – that contain this type of port, or even devices with SSD Thunderbolt NVMe drivers, may be considered.

At the moment, the company is working on a definitive fix for this bug, but it is unlikely to arrive in time for the next patch released.
