There are two notable known issues with the update:

  • After installing this update, XPS Viewer might be unable to open XML Paper Specification (XPS) documents in some non-English languages, including some Japanese and Chinese character encodings. This issue affects both XML Paper Specification (XPS) and Open XML Paper Specification (OXPS) files. When encountering this issue, you may receive an error, "This page cannot be displayed" within XPS Viewer or it might stop responding and have high CPU usage with continually increasing memory usage. When the error is encountered, if XPS Viewer is not closed it might reach up to 2.5GB of memory usage before closing unexpectedly.
