You can use a negated character class [^ ] here. 

^[^\\/*?:"<>|]*$

Regular expression:

^                  # the beginning of the string
 [^/*?:\"<>|]*     # any character except: '\', '/', '*', '?', ':', '"', '<', '>', '|' (0 or more times)
$                  # before an optional \n, and the end of the string
