Windows 7 UAC a Security Risk?

I just got done reading a blog post about how you could with an easy to make script disable UAC all together. According to Long Zheng, he states that how a malicious software could circumvent the UAC by turning it off.   I simply love the new look and feel of the UAC and hope they can come up with a way to fix the problem. [ad#ad2-right]According to him there is a way to fix this and keep all the new features set.  He has provided the proof of concept for turning of UAC without having it ask. You can download it yourself and try it out, but be careful it will disable UAC.
I hope Microsoft fixes this little flaw and makes it more secure than Vista.  According to Microsoft though, they claim UAC functionality is “by Design“.  I don’t know if it is or isn’t but I do know that it could easily let more Malware into Windows 7 before it got enough people on board.  That is one of the reasons I don’t want Windows 7 Released now.  I don’t want this to become a failure in the minds of people.  I want to look back and see this being successful. Hopefully Microsoft fixes this and makes it even more secure in the future.
