Administrators (not the same as the built-in Administrator) are just about the same as a standard user, but will get a UAC
prompt, if UAC is turned on, to give confirmation before being allowed to make changes that affect the system or other users. Standard users
will get a UAC prompt to provide the administrator's password before being allowed to do so. If UAC is not turned on, then the standard user will not be allowed to do so.
It is not recommended to use a user account that has full unrestricted access of the full computer without getting a UAC prompt since everything, such as malware, that runs while logged into this account would also have full unrestricted access.
Saying the above, you could enable the built-in Administrator account
and log in to it, or elevate the privilege level of administrators
to be the same as the built-in Administrator account to have full unrestricted access.
Hope this helps,
