Many of the commands listed below are also discussed in more detail elsewhere on this site as is indicated by the link "details here". Most commands have switches that are not given in the table. For more information, open a command prompt and enter "commandname /?" (without quotes). Detailed information about these commands and a larger list is available at this Microsoft reference. These commands are in Windows XP, Vista, and Windows 7.
The complete list of possible commands is quite large. Collected here is a selection of those that I believe are likely to be the most applicable to home PC use.
