There are third-party utilities to manage items in / Windows / Start Menu
-- but this is something you can do yourself.
Each menu in / Start Menu is merely a subfolder holding
LNK = link files to installed applications: and you can
cut and paste these files and folders like all other standard
files and folders.
E.g. create one new folder c:\windows\start menu\programs\graphics.
Then MOVE into it all the folders for graphic files already in
e.g. CorelDraw, MSPaint, Photoshop, Broderbund Print Shop.
This will make your total /Programs list shorter: and group
together all the graphics apps you have. You can do the same
for audio players and any other type of app where two or more
installed programmes have similar functions.
