Windows 7 windows xp mode missing

[ldocker]

I have a new Dell laptop that came with Windows Virtual PC and have used the Windows XP Mode several times. I was going to use it and noticed my Windows Virtual PC and Windows XP Mode icons are missing from the start menu. Windows Virtual PC and the Windows XP Mode Applications are the only things showing. I have tried reinstalling but can't find it. If I try to reinstall it says it's already installed. Help
