A bit of an exaggeration here.i could steal all your data with this profile on your pc.
Windows Firewall is not removed.not even a firewall
What I agree with is that you shouldn't use an Administrator account, I don't know why people like to use that, besides everything running elevated even those who don't need it will have several bugs with several programs that were made during or after the era of Windows Vista. Example: Drag and drop files in VMware. Besides others that I don't remember.
There are so few UAC popups, this was annoying only in Vista but from 7 onwards it's quite acceptable. Much better than accidentally running a script that ruins your OS. But for those who insist on disabling it, it's much better to just disable the prompt:
In NTLite go to Settings -> User Account Control (UAC) -> UAC Admin prompt and put "Elevate without prompting"
And NTLite is an advanced tool, you have the freedom to remove things that will break the OS, it's your responsibility of the consequences. Those who use this tool must be aware of this.
