KemUtil.dll error

Occasionally drivers and programs start to act weird. As someone once said .. " My software doesn't have bugs, it just develops random features". It was this thing that happened this morning to a friend.

When he started his PC, Vista based ..there was an error with the KemUtil.dll . This driver actually belongs to Logitech, and comes with many of their harware ..for example a mouse, keyboard ( as was the case), graphic tablet etc. To get rid of the error you may try one of the following:
1) simply unplug and then plug back in the piece of hardware that you have from Logitech.
2) Reinstall the driver
3) If it's something plug and play you can uninstall the driver altogether and see if that works.
