Our DXC technical team are continuing investigation into this issue with Microsoft, they have collected diagnostics and we are now waiting for them to confirm the next steps and hoping for a fix or further security update to be released.
As a reminder: Whilst we seek a solution from Microsoft, the workaround for affected customers is to 'Save' the document being downloaded, instead of opening it directly. Customers can then open the file from their Downloads area on their computer without issue.
A further update will be issued no later than 12:00 tomorrow.
DXC apologises for the inconvenience and the impact being caused to our customer's operations.

DXC has been made aware this morning of a small number of customers having issues downloading files, via Microsoft Edge, from either IMR or KnowledgeBase. We have traced this to a specific Microsoft security update that has been downloaded to customers' Window 11 machines, which was released in the last few days.
For the information of customers' technical teams, the Microsoft update is known as "2025-09 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5065426) (26100.6584)".
