I am having an issue with icons not appearing on my task bar. Specifically, Windows Store and Windows Reader are invisible. The places where they should be on the task bar are still reserved, and when you click on the blank spot, the program opens. If I open certain programs or games, they also do not appear on the task bar. iTunes and OpenOffice both show on the task bar when opened, but downloaded applications will not. All of the Reader files just show a blank piece of paper in the files folder, but the files still work. I also have some mp3 files that used to have specific icons, but now they just show the default blue music note. This isn't really affecting my ability to use the computer, but I am concerned that it is just the beginning of a larger issue. I've tried restarting the computer into safe mode and running malware program, but it's coming up empty. I attached a screenshot of what im talking about. My desktop icons are fine, as are some of the task bar icons. Anyone know what could be causing this?
