Microsoft has finally published an optional update to address
at least four major bugs in Windows 10 version 2004, including
Storage Spaces file corruption issue where the disk-failure
protection feature is broken.
As we reported in June, users claimed that Windows 10 May 2020
Update could corrupt your files when you use the
Storage Spaces ‘parity spaces’ feature, while others noted
problems with disk defragmentation or Drive Optimize tool.
Windows 10 version 2004 bug corrupted partitions and damaged
files in Storage Spaces’ party spaces and some users noted that
their 20TB of data show up as ‘RAW’. Others reported multiple
errors when attempting to open the Storage Spaces management
from Settings or Control Panel.
While the problem with Drive Optimize tool remains unpatched
and unacknowledged, Microsoft says it has included fixes for
problems affecting Storage Spaces in
Windows 10 Build 19041.423 (KB4568831) optional update.
This patch also allows Windows built-in data protection
software to work as intended.
Windows 10 KB4568831 is an optional patch and it won’t install
automatically. If you don’t install the patch now, you’ll get
Storage Space and other fixes in next Patch Tuesday update,
which takes place on August 11.
You may still see a compatibility hold on the Windows 10
version 2004 if Microsoft determines that your machine uses
Storage Spaces or older drivers.
The current status of the upgrade block
In addition to Storage Spaces, Microsoft says the following
issues have been resolved or mitigated in this optional update:
- Issues with devices using older drivers of Nvidia GPU.
- Problems when connecting to more than one Bluetooth device,
such as a mouse, keyboard or headset.
- Variable refresh rate may not work on devices with Intel
While these issues have resolved or mitigated, Microsoft says
compatibility hold for devices with above issues will be lifted
These fixes will allow Microsoft to finally expand the rollout
of Windows 10 version 2004 and Windows Server version 2004.
