Security News > 2023 > May > Microsoft: Windows issue causes file copying, saving failures

Microsoft says some 32-bit applications are impacted by recurring failures when saving and copying files across multiple Windows versions.

The intermittent issue only affects apps that are large address aware and are also using the CopyFile API on Windows 11 21H2 and 22H2 or Windows 10 21H2 and 22H2. "Windows devices are more likely to be affected by this issue when using some commercial/enterprise security software which uses extended file attributes," Microsoft said.

Out of all affected Windows versions, Microsoft is yet to address the file copying and saving failures on the latest release, Windows 11, version 22H2. However, the company says impacted customers can work around the issue by saving or copying the files again until a fix is ready.

Microsoft has already fixed the issue on Windows 10 and Windows 11 21H2 via Known Issue Rollback, a Windows capability designed to revert buggy non-security fixes pushed through Windows Update.

Windows admins must install and configure a KIR Group Policy on all affected enterprise-managed devices to resolve these file transfer and saving problems.

To deploy the Known Issue Rollback, you must go to the Local Computer Policy or the Domain policy on your domain controller using the Group Policy Editor to choose the Windows version you want to target.
