Replace illegal WIndows characters


I have bene playing around with regular expressions, and browsing, but can't seem to get this working:

I wnat to remove ALL illega characters form all TAGS, filename etc that are present in my music collection.
The illegal characters are: / ? < > \ : * | ” '

I wnat to replace them with _ (an underscore)

Te reason: my music colelction has been build up on a LInux based (embedded) system, and I want to port it to WIndows. But that menas that TAGS/filenames with teh illega characters need to be changed.
(Yes, I need to change the TAGS to, as my Music Syteme, Hifidelio, uses them to automatically generate filenmaes an ddirectories.....).

Can anybod help? pls....
