Microsoft has fixed issues causing Microsoft Connected Cache (MCC) node discovery on enterprise networks. Microsoft Connected Cache Issue was with the Windows devices that use DHCP Option 235 to discover Microsoft Connected Cache (MCC) nodes in their network, which might be unable to be used.
Microsoft released the July 2024 KB5040525 preview update for Windows 10 to fix an update issue that broke Microsoft Connected Cache (MCC) node discovery on enterprise networks.
This issue occurred after installing the January 2024 non-security update (KB5034203), released on January 23, 2024, or later. Due to this issue, Windows devices will download updates and apps from the public internet, and IT administrators will see increased download traffic on their internet routes.
