Displays the data stored in a Registry value, where keyname is the full path of a registry key and valuename is the name of the value to query. Omit /v valuename to display list of all the values in keyname or specify /ve to query the (Default) value. Include /s to query all subkeys and values as well. Keyname can also include the name of a remote computer like this: query computer\keyname.

add keyname [/v valuename | /ve] [/d data] [/t typ] [/s sep] [/f]

Adds a new value. The keyname, /v, and /ve options are the same as with query, above. The /d option assigns data to the new value; if omitted, the new value will be empty.
