After all the "push-back" Microsoft got about UAC it's seems it has decided to leave it broken and abandon all efforts to make their OS more secure. Rather than actually fix UAC Microsoft just turned down the default protections. Making it useless!
If there is anything worse than having no security on Windows it's having useless security while at the same time claiming the system is secure. Microsofts attitude to security absolutely stinks. They have acknowledged this fault and said it won't be fixed because it exists by "design". Just like Microsoft intentionally made UAC annoying.
Is it just me that's thinking Microsoft is suicidal?
