Aqui está o comando completo usado para iniciar o processo do IDE em minha máquina (descoberto pelo excelente Process Explorer ). Obviamente, o seu próprio será um pouco diferente.

Os atalhos acabam se limitando a um certo número de caracteres, e tudo o que não caberia. Eu tentei criar uma variável de ambiente para manter tudo ao invés, mas as variáveis de ambiente eram de tamanho limitado também (embora não tão drasticamente), então acabei criando duas delas.
Acabei com um alvo de atalho de "C:\Program Files\Java\jdk1.6.0_17\jre\bin\javaw.exe" %NB_PARAMS1% %NB_PARAMS2%
iniciando em "C:\Program Files\NetBeans 6.8\"
e parece funcionar bem.
Se você quiser que seu atalho tenha o ícone certo, ele poderá ser alterado para o ícone do iniciador facilmente.
