Known issues in this update

Symptom

Workaround

Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.

Do one of the following:

  • Perform the operation from a process that has administrator privilege.

  • Perform the operation from a node that doesn’t have CSV ownership.

Microsoft is working on a resolution and will provide an update in an upcoming release.

When setting up a new Windows device during the Out of Box Experience (OOBE), you might be unable to create a local user when using Input Method Editor (IME). This issue might affect you if you are using the IME for Chinese, Japanese, or Korean languages.

Note This issue does not affect using a Microsoft Account during OOBE.

This issue is resolved in KB4534308.

After installing this update, you might encounter issues with applications that use embedded HTML and SameSite cookies across sites or iframes.

To align with industry partners, the default behavior of the SameSite cookie header in ASP.NET has been changed. To mitigate this issue, see Work with SameSite cookies in ASP.NET.

How to get this update

Before installing this update

If you are using Windows Update, the latest SSU (KB4523203) will be offered to you automatically. To get the standalone package for the latest SSU, search for it in the Microsoft Update Catalog.
