Lock down Windows with user account control . This technology can also be used to help you protect the safety of Windows . User Account Control ( UAC ) is intended to make Windows safer by alerting a user when a program wants to make a change to the computer . This will result in multiple pop-ups when you make a change to the computer . Although it is a good idea , the operational process of UAC makes most of the users crazy . Some users choose to turn off UAC to prevent this trouble in the end , but in the meantime they won’t be alerted when any program make a change to Windows . So though it is a little troublesome , I urge you to keep UAC turning on unless you want your computer compromised .
