Administrador sem privilegio

Boa noite galera,

recem formatei meu computador, e nao tenho mais a menor ideia do que pode estar acontecendo..

Nao consigo mexer em nada na pasta do windows, nem arquivos de progama, nem tarefas simples de administração do sistemas.

Sempre as mesmas mensagens, "acesso negado", "voce nao tem privilegios de administrador", etc etc..

Acontece que eu sou administrador.. e ja tentei TUDO que os senhores imaginarem e acharem na internet sobre o assunto..

1 - Clicar em propriedades -> segurança e dar os controles pro usuario que eu kero no diretorio q eu kero nao funciona.. simplesmente pq da acesso negado..

2 - tentei liberar o administrador em cmd: net user administrador /active:yes (ja ate decorei o comando), liberou o admin numa boa.. mas a conta MASTER-ADMIN-SUPER-MEGA-f*** do windows tambem nao tem

privilegios o suficientea

3 - modo de segurança.. nops.. fail..

4 - executar - lusrmgr.msc nao funciona.. acesso negado..

Ou seja.. nao consigo fazer nada.. ja to desesperado.. nao kero formatar esse negocio de novo.. ja formatei TRES vezes..

ou eu estou comendo muita mosca, ou alguem tem q me ajudar aki no forum imasters rsrsrs...

Segue um log no hijackthis se ajudar:
