User Account Control (UAC) improves security for all users. The main purpose of UAC is to protect the computer and reduce the exposure and attack surface of the operating system by basically starting with all users running in standard mode.

An administrator can run most applications, components, and processes with limited privilege, but also has the ability to elevate or increase the privilege for specific administrative computer tasks and application functions. This added permission management also prevents malicious software from running unnoticed on your system.

 
While turning UAC off may be necessary when troubleshooting QuickBooks Desktop issues, it is highly recommended that you turn it back on to prevent security risks on your computer.
