Microsoft has warned Windows 10 users who have installed the company’s latest updates may have issues updating their Microsoft Office products. According to TechRadar some Windows 10 users who downloaded Microsoft’s October 2020 Patch Tuesday updates received an error when trying to update their Microsoft Office installation.
The error message they receive is “Download of Office 365 file failed, error =”.

The problem is that Microsoft has not provided any fix for this issue, which means that users will need to uninstall the Windows update that is causing this issue, then update their Office installation, before re-installing the Windows update.
Microsoft Engineer David James previously tweeted that the bug appears to be caused by a certification error.
This in turn stops Configuration Manager from being able to download Microsoft Office updates.
“Only workaround for now until a fix is released, is run the Admin UI on a machine that isn’t patched to 10b; and manually sync the o365 patches,” tweeted James.
