Mark Russinovich tem um excelente artigo sobre como contornar as mudanças na Política de Grupo .
Group policy settings are an integral part of any Windows-based IT environment. If you’re a network administrator you use them to enforce corporate security and desktop management policy, and if you’re a user you’ve almost certainly been frustrated by the limitations imposed by those policies.
