Hello,
The registry editor is set to use the most amount of privilege that is
assigned to your user account.
If you are logged in as an administrator, regedit will end up with full
admin privileges, and so it prompts for your consent.
If you are NOT an administrator, regedit will run with however much
privilege that is assigned to your user account. Since this does not equal
admin privilege, it does not require a prompt.
You can always right-click regedit and click run as administrator if you
want to elevate it to admin privileges from a standard user account.
There are many more system utilities that work like this, and this is why
you will experience less UAC prompts when logged in as a standard user.
