Microsoft's November update for 726 Windows flaws fails to install for some users, The Register reported. Microsoft had not said why.
The update came out on Patch Tuesday, Microsoft's monthly security update day.
It addresses 726 security flaws in Windows alone.
Within hours, users reported that downloads and installations were failing with error messages.
When the report ran on 11 November, Microsoft listed no known issues for the update and had made no statement. The Register said it had asked Microsoft to comment.
One user on a Windows user forum said that turning off Windows Sandbox, a built-in space for testing software, and restarting let the update install. Others saw failures either way. Other users reported checking the update with Microsoft's built-in repair tool or downloading it by hand.
In September, Microsoft rushed out an extra fix because that month's Windows security update caused trouble for Remote Desktop Services, which lets staff use a computer from elsewhere.
Computers where the install fails stay without this month's fixes, so IT teams need the list of computers where it failed.
