Last week, Microsoft released an update for Vista’s Windows Defender software and some people reported that their mice and keyboards stopped working after they installed the update.

“We are aware of concerns that a recent Microsoft update may be causing problems with USB devices. We are investigating the matter, and at this time, do not have any information to share,” said Microsoft in a statement.

Microsoft released the update because there is a security hole in Windows Defender and the update was supposed to fix the situation.

There is no news when they will release a patch to fix the USB device problem.
