What you need to understand is even if you are using an account with admin privilege (except, I believe, the hidden admin account itself) you do not have admin privilege unless you invoke it explicitly.
If you want to run a given .bat file with admin privileges the easiest thing to do is to create a shortcut to the actual .bat file (most often on the desktop, but it could be anywhere) then opening the shortcut properties, activating the Advanced button, and checking the checkbox for "Run as administrator." I use this technique for several scripts that need to reset the system date temporarily, which you cannot do except if running as admin in a batch file, and then change it back. The "Run as administrator" advanced property is only present, to my knowledge on shortcuts, not native .exe files, .bat files, or .ps1 [PowerShell script] files.

In a modern society where everyone thinks their opinion deserves to be heard nothing annoys me more than individuals who mistake their personal preferences for fact.
