Microsoft Issues 6th Cumulative Update for Windows 10 Version 2004

Posted on April 10, 2020 by Paul Thurrott in Windows 10 with 5 Comments

Over four months after it completed Windows 10 Version 2004, Microsoft keeps updating the unreleased OS with bug and security fixes.

News of the 6th cumulative update for Windows 10 version 2004 arrives, as always, via Microsoft’s Windows Experience blog, which notes that the update is now available to Windows Insiders in the Slow ring. Many waiting for the software giant to move Windows 10 Version 2004 into the Release Preview ring, which is typically the final major milestone before general availability to the public. But with Patch Tuesday coming up in just a few days, it’s reasonable to wonder if this new release will be pushed back to May now.

While we ponder about that, here’s a list of what Microsoft says is fixed in this CU:

  • An issue that prevents older versions of certain apps from opening by directing users to install the latest version of these apps.
  • An issue that fails to allocate resources during device initialization, which causes certain USB mass storage devices to stop working.
  • An issue that prevents the mute button from working on certain devices with the Your Phone app.
  • An issue that causes a fault in the input-output memory management unit (IOMMU) and a DRIVER_VERIFIER_DMA_VIOLATION (e6) error. This issue occurs after resuming from hibernate on systems that have Kernel Direct Memory Access (DMA) Protection and Dynamic Root of Trust Measurement (DRTM) enabled.

Additionally, the firm says it has updated the Country and Operator Settings Asset (COSA) to increase the coverage for automatic cellular provisioning on PCs with mobile broadband.
