Windows 10 Version 21H1 Build 20262.1010 (KB4594431) Is Out for Dev Channel


Windows Insiders in the Dev Channel received a new Preview Build on Wednesday that brought quite a long list of fixes. This Channel is currently testing features for the 2021 Windows 10 feature updates. Builds currently being tested by the Dev Channel Insiders aren't tied to a specific version, but are likely to be associated with version 21H1.

Today, Microsoft has released Windows 10 Cumulative Update Build 20262.1010 (KB4594431). This release isn't bringing anything new as the Windows team writes it "is designed to test our servicing pipeline."
