Make a screendump of what you are actually seeing?
Just cleared down the start menu's recently used files list to see if I can work through the problem and now the problem seems to have gone away - typical. So no screenshot available which is any use and I cant replicate it - So i guess problem solved.
Just to elaborate further with the description - I would click start from the desktop, scroll up to Premiere CC, expand the black arrow on the right to show recently used files, and instead of just getting the .prproj files listed I would see.... .wmv, .xmp, .mov, .mpeg basically anything I'd imported or used inside a premiere project. Perhaps this is normal and I haven;t noticed it before but I'm sure the list would normally only show prproj files in previous versions of premiere???.
I'll screendump and relive this if it comes back. Thanks for your help
Start the program first, then you'll see the recent projects right in the start screen.
