Very often these days we need to manually choose to run a program as the computer's "Administrator" (or "Admin" for short). What this is for is so that the program is able to perform certain actions that it normally cannot do when not being run as the Administrator. One example (of many) is to perhaps start and / or stop a Windows Service. There are 2 ways do do this, one is a temporary "one time use way", and the other is the permanent way.

The "temporary" way is meant to be used if you only really need to run the program as Admin one time, or just every so often.
