Right click on taskbar » properties » start menu » customize » large icons.

It's a windows thing not OD.

No, that's not it. They are already set to "Large Icons", but nevermind, I figured it out! It's an IconPackager "trick". Change the icon size to something else besides the default 32.

You do realize that if you had said "I have "large Icons" enabled in the start menu and they aren't" that I never would have bothered posting the solution for what you asked. Information helps. Yes, I am a little testy right now.

Maybe I should have worded my question differently, but I thought that the "(bigger than normal "large icons") (64x64?)" part would have said that I meant larger than the "normal" large icons or that I already had "large icons" enabled. Sorry about the confusion/misunderstanding

mr tee needs a lolly,
you didn't word your question too awfully.
you're right though, just change the size of the icons with ip.

Use Iconpackager

Settings>Icon Size>64Pixels

ok here's the best way to assign size to each icon in start.
in IP, click on icons and cursors. select "start"tab, and highlight the icon you want to change, click "edit" icondeveloper opens up and you can select the size you want for that icon. go down the list of start icons and assign each one the size you want it to be.
I am unsure if this will change the icons that show up in the start panel outside the ones pinned there.
