[Introduction]<\/b><\/p>\n

<\/p>\n

We are updating archive file classification behavior on Windows endpoints to align with cloud workloads. This change improves consistency, reduces noise in event reporting, and enhances performance when processing archive files.<\/p>\n

[When this will happen:]<\/b><\/p>\n

<\/p>\n

The change will begin rolling out late November 2025<\/b> and will apply automatically.<\/p>\n

[How this affects your organization:]<\/b><\/p>\n

<\/p>\n

    <\/p>\n
  • Who is affected:<\/b> All organizations using Windows endpoints with archive file classification enabled.<\/li>\n

    <\/p>\n

  • What will happen:<\/b>
    \n
      <\/p>\n
    • Outer archive files (e.g., .zip, .rar) will now be classified directly.<\/li>\n

      <\/p>\n

    • Classification will be atomic for improved consistency and reduced latency.<\/li>\n

      <\/p>\n

    • Internal files within archives will no longer generate individual events; only the outer archive file will be reported.<\/li>\n

      <\/p>\n

    • Context and label-based rules will not apply to files inside the archive.<\/li>\n

      <\/p>\n

    • No admin or user action is required for this change to take effect.<\/li>\n

      <\/ul>\n

      <\/li>\n

      <\/ul>\n

      [What you can do to prepare:]<\/b><\/p>\n

      <\/p>\n

        <\/p>\n
      • No action is required.<\/li>\n

        <\/p>\n

      • If you maintain internal documentation on classification behavior, consider updating it to reflect these changes.<\/li>\n

        <\/ul>\n

        [Compliance considerations:]<\/b><\/p>\n

        <\/p>\n

        No compliance considerations identified, review as appropriate for your organization.<\/p>\n<\/td>\n<\/tr>\n
