LibRaw library is targeted for developers, not for end-users.
Any questions related to MS' explorer extension should be asked to MS, we're not responsible for this product and not able to change anything in it. In this case Microsoft is one of our users (developer who use LibRaw).
If your problem is related to LibRaw library itself (you're software developer who uses LibRaw) we'll try to help.
