I am not sure how this happened, but I can't find a fix from searching the interwebs. All of a sudden my Jump Lists for VS2015 (other programs work fine) show the generic icon. Has anybody ran across this and know a fix? FWIW I am running Windows 10 Enterprise.
Ok, So I enrolled into the Windows Insider Program and after updating to Windows 10 Insider Preview Build 14366 I got my icons back. So it appears that at some point this was patched by Microsoft.
