Microsoft has confirmed a new known issue causing customers to experience a significant performance hit when copying large files over SMB after installing the Windows 11 22H2 update.

"There is a performance reduction in 22H2 when copying larger files from a remote computer down to a Windows 11 computer or when copying files on a local drive," explained Ned Pyle, Principal Program Manager in the Windows Server engineering group.

"You are more likely to experience this issue copying files to Windows 11, version 22H2 from a network share via Server Message Block but local file copy might also be affected."

Microsoft also shared a workaround for customers affected by this known issue after updating their devices to Windows 11 22H2. As Redmond explains, impacted users can mitigate the file copying performance hit over SMB with the help of file copy tools that don't use cache manager.

Since Windows 11 22H2 was released, Microsoft has added compatibility holds to block the upgrade from being offered on some systems due to printer issues or blue screens.

The company also confirmed this week that the Windows 11 2022 Update is also breaking provisioning, leaving Windows 11 endpoints partially configured and failing to finish installing.
