I keed getting this message. If I press cancel or continue it goes away but then comes back up again later. I have no idea why this has started to happen. Can anyone please help with a solution.

Hi, The issue may occur if you have a removable drive configured as drive letter C. Please try to change the drive letter as bellow. Change, add, or remove a drive letter http://windows.microsoft.com/en-US/windows7/Change-add-or-remove-a-drive-letter Niki Han TechNet Community Support

If you have a CF card slot or some other drive with no disk present and you have software that is scanning that drive, say a virus scanner, you'll get that message also.

It says that Some programs make references to specific drive letters. If you change a drive letter, these programs might not work correctly. I don't know what to do plz help!!
