Deactivating user account control can be useful when errors occur in certain programs.
User account control is not exactly a first-class security feature, as it only encourages users to make significant changes to their computer when they are about to do so. Disabling it, if necessary, disables some of the annoying prompts that appear when you open the system tools.
- Open the Control Panel by searching for it in the Start menu. You can also use the Windows + R key combination, type “control.exe” in the “Run” window that appears, and then click OK.
- Change the “Show By” option in the Control Panel to “Large Icons” and find the “User Accounts” option by scrolling or looking down.
- Open it and click on “Change User Account Management Settings.”
You’ll notice that there are several different levels that you can select on the security slider.
- Try reducing that value by one if it’s on the highest slider, and see if that helped after you run the problematic program. Repeat the process if the error still persists.
- We recommend disabling user account management for a while, as it is likely that the program should run successfully, and then try to reactivate it.
