Windows 10 2004 gets Storage Spaces fix with update KB4568831

Microsoft has fixed the Storage Spaces problems with Windows 10 version 2004. The fix is available now as preview, and it'll be availble to everyone in the coming weeks.

Windows 10 2004 Storage Spaces

Microsoft finally releases permanent fix for Storage Spaces problems on Windows 10 version 2004 (May 2020 Update). During the early days of the May 2020 Update rollout there has been a lot of complaints with the operating system after the upgrade, including a couple of problems with Storage Spaces that prevent users from creating storage pools using Control Panel and data integrity issues when using the parity feature.

Storage Spaces is a feature that allows you to group multiple drives into pools, which you can then use to create storage spaces with different types of RAID-like technologies, such as mirror and parity, to help protect your data from drive failures, and expand storage over time.

Once the company acknowledged the problem, it also offered steps to mitigate and recover files on affected devices, and now, it appears that a permanent fix is on the way.

On July 31, Microsoft made available a preview of the next cumulative update (KB4568831) expected to arrive during the August 2020 Patch Tuesday, and the list of improvements and fixes (buried at the bottom of the page), you can find two fixes specific to Storage Spaces, including:

  • Addresses an issue with in-memory parity bitmaps that can cause data integrity issues on Parity Storage Spaces.
  • Addresses an issue that prevents the creation of a storage pool using Manage Storage Spaces in Control panel.

If you have been affected by this problem, the fix is coming soon. However, if you can’t wait, it’s also possible to download and install update KB4568831 manually using these links.

After downloading the update, you only need to double-click the installer to apply the update. However, before the installation, remember that the update is in preview, which means that it’s not yet fully ready, as such, you should install it at your own risk.
