Win10 Realtek HD Audio update failed to do

Close UAC method one:
The user blazinsmokey found that after closing the UAC user account control, the driver update can be installed normally. It seems that the driver needs to be upgraded during the installation process. When the permission is granted, the UAC user account control window does not pop up normally, and the program cannot continue to be installed.
If you have encountered similar problems, you can temporarily turn off UAC to solve.
Enter UAC in the taskbar search box, press Enter to open the user account control settings, as shown below:

Set the security level to the lowest (ie, never notify ”) can.
Close UAC Method 2:
If you have Rubik's Cube installed, you can also close UAC by the following method:
Click on the "Set Wizard" in the Rubik's main window, and then in Security Security & rdquo; Lieutenant UAC can be closed

It is recommended to re-open UAC after the problem is solved, most of the software can run normally under lower authority. After UAC is enabled, all operations that require administrator rights need to pass the user. Agree, this can effectively resist malware installation of redundant software or tampering with system files without the user's consent.
