My apologies to the CB Team. The CB 16.01 installer did replace the old 13.12 file in Windows 10 from Programs and features. It also removed it from the Windows Programs files.
However it left the codeblocks 13.12 mingw-setup file behind. This may be an add on to CB with the codeblocks 13.12 name placed in front of the files name, its probable from MinGW. This is a big file 100207k. I recommend other users delete it if they have load CB 16.01. The newer version was included with the CB 16.01 install.
