How should you take down a computer running Windows 2008 Server?

The recommended method for taking down a computer running Windows 2008 Server is to shut it down using the operating system. This approach ensures that all running processes and applications are properly closed, which helps prevent data corruption and loss. Using the operating system's shutdown procedure allows the server to safely save any changes, complete any necessary write operations, and stop hardware components in an orderly fashion.

By following this method, you maintain the integrity of the server’s file system and the data stored on the system. The other methods, while they could technically result in a powered-off state, would increase the risk of data loss and corruption. Unplugging the power or removing the power cord does not allow the system time to properly close any operations or save changes, which poses a significant risk, especially for servers that handle critical data or functions.
