You can disable the—sometimes annoying—User Account Control (UAC) prompts for members of the Administrators group, while leaving them active for limited user accounts. This is great if you don’t want others accessing or changing system settings. Disabling the alerts, however, requires editing the Windows Registry:

Hive: HKEY_LOCAL_MACHINE
Key: SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
Name: ConsentPromptBehaviorAdmin
Type: REG_DWORD
Value: 0 Enable, 1 Disable
