Não consigo executar regedit

Bom dia.

Tenho instalado o Windows 8 em uma máquina de meu escritório e de um tempo para cá sempre que tento acessar o registro me retorna uma mensagem: "C:\WINDOWS SYSTEM32\ulib.dll não foi projetado para ser executado no Windows ou contém um erro. Tente instalar o programa novamente usando a mídia de instalação original ou contate o administrador do sistema ou fornecedor do software para obter suporte. Status de erro 0xc000012f"
Já tentei executar como administrador, tentei também entrar com um disco de boot e notei que o arquivo dll não deleta, então renomeei ele e coloquei um outro ulib.dll, mas ao fazer isso a máquina deu erro ao reiniciar, então recoloquei tudo como estava e a máquina reiniciou normalmente mas continuo sem conseguir acessar o registro, o firewall também não habilita de jeito nenhum e não consigo reiniciar em modo de segurança nem com prompt.
Não sei mais o que fazer e gostaria de saber se alguém tem alguma ideia do que pode ser, se um virus ou coisa parecida.
Desde já agradeço.
