The reason this is not recommended is because the UAC actually does serve an important purpose: It alerts you to any programs that might be trying to change your computer, including viruses and malware links you may have accidentally clicked on. You can disable the User Account Control pop-ups altogether, but this is not recommended - not even for veteran PC tinkerers. Well, there is one way, but it's not secure.
While you can set up specific programs to always run in administrator mode (thereby bypassing this pop-up), there's no easy, secure way to set up your computer so that all programs run in administrator mode. If you frequently run programs in administrator mode, dealing with the User Account Control (UAC) - the pop-up window that asks you if you're sure you want to let this program make changes to your computer - can get annoying. These security windows can get annoying, but it is not a good idea to turn them completely off.
