With every version of Windows up to Windows XP, users are, automatically, administrators. What this means is they've complete control over everything in the operating system and may install programs and delete or move files without restriction. This really is still the situation with Windows 7, but User Account Control (UAC) adds a layer of protection.
Due to problems running legacy software in Windows, the entire security owned by other os's, for example Apple OS X and Linux, isn’t possible. But Windows developers recognize that users may occasionally make changes towards the operating system either unintentionally or without comprehending the true repercussions. More importantly, Windows developers know that malicious software and viruses may wish to do that too!
UAC aids in preventing inadvertent or malicious changes to critical system processes by placing a security layer between your user and then any action that Windows determines might lead to injury to or destabilize the operating system. When UAC is activated with a questionable action, Windows 7 drops right into a secure desktop where just the UAC dialog box is active and where merely a user, not software, can make a variety.
UAC is really a useful although not a foolproof method to protect Windows 7 from attack. As comedy sci-fi author Douglas Adams once famously said, “A common mistake people make when attemping to create something completely foolproof would be to underestimate the ingenuity of complete fools.” While this observation does not look at the inescapable fact that so many people are often bemused or confused by technology, it will affect some extent to UAC.
It’s still too simple for a person to click Yes without reading or properly comprehending the implications of creating this type of decision. What isn’t helpful is that UAC messages are often unclear, also it can be a challenge to determine which is attempting to alter what. Hopefully, this can change in the next edition of Windows due in 2012, until then there's a potential weak link in Windows security that you should be conscious of.

But bear in mind that setting webmaster password may have a downside. Password protection for that administrator account prevents users from making even legitimate changes to Windows or another software that are usually necesary.
