[OFFER] MS Windows Services for UNIX 3.5
It seems I have recycled or lost the sheet of 2.0-serial (another discussion here in offers/requests). But luckily I found Version 3.5 in my pile of CDs, it does not need a serial.

Interix is the ancestor of this product, WSFU is still called Interix in many places. I also uploaded it earlier and posted here.
