KB4568831 Parity Storage Spaces fix for Windows 10

Do you remember the Storage Spaces bug that came up after some users updated to Windows 10 version 2004?

There wasn’t anything most of the affected users could do about the issue. Even Microsoft cautioned against using the chkdsk command to address it.

Well, the Redmond tech giant announced that it fixed the bug with the recently released cumulative update KB4568831.

Windows 10 Storage Spaces problem

Parity Storage Spaces serves as a drive backup feature that comes to the rescue when one of your storage devices fails. But this option became unavailable or began to malfunction after some PCs updated to the latest version of Windows 10 over a month ago.

Then, Microsoft pointed out that, with certain configurations, Disk Manager would display Parity Storage Spaces partitions as Raw.

You should be able to get rid of the problem now by installing CU KB4568831. Microsoft isn’t automatically pushing this update though, so you need to download and manually install it.

It’s understandable that many affected users may have expected to be able to upgrade to the May 2020 Update right away, now that what prevented them from doing so is gone.

But they can’t do that just yet, according to Microsoft.

When the tech giant acknowledged the Parity Storage Spaces issue, it also put affected devices on a compatibility hold.

To safeguard your update experience, we have applied a compatibility hold on these devices from installing or being offered Windows 10, version 2004.

Apparently, the update block remains in force until mid-August, and to make matters worse, it has no workaround for now. This means that DIY alternatives like installing the OS with the Microsoft Media Creation tool would most probably fail.

In the meantime, Microsoft is automatically delivering the new OS to more Windows PCs that are approaching end of service.
