Only way I know how is to run in Standard User mode. My account (Mitch) is Standard and my other account (Midway) is Admin. I mainly run in a standard account and have an admin account as well though I very rarely go into it. Whenever I need to install a program or change system settings the UAC window comes up and I have to enter Midway's password. It works just like it does in Linux.
Most Windows users will be annoyed by this setup but if you spent any time in Linux you already used to it and appreciate it's security.
