Microsoft removed clip art from Windows because the images have become increasingly outdated in comparison to online image search engines, which can aggregate better quality images that are more up-to-date. The company suggests using a Bing image search as an alternative to clip art.
Microsoft announced in late 2014 that it would remove its Office Clip website, which hosted selections of clip art images. The company cited a steady decline in traffic as users turn to online image searches for more accurate and applicable images. PC World reports that Microsoft announced the removal of clip art from Word on its Office blog, but then later removed the post. As of December 2014, traditional clip art is still available in Word 2013.
