UAC frequently pops up because the running program requires administrator permissions or the system setting level is too high. Common reasons include installation of software, modifying system settings, running third-party tools and other operation triggers. If using an administrator account, UAC only confirms the operation and not blocks. The methods for reducing prompts include: canceling the program to run as an administrator, lowering the UAC notification level, using a standard user account, and starting the program through the task planner. It is not recommended to turn off UAC completely because it can effectively prevent malicious programs from tampering with the system. You can set the UAC to "notify only when the program changes the computer" to balance security and experience.
