SoftICE/W (for Windows) was developed in the 1990s, and was instrumental in the Writing of "Undocumented Windows", by Andrew Schulman, David Maxey and Matt Pietrek. SoftICE/W was derived from an earlier, lesser known product, SoftICE for NetWare (32-bit protected mode). One of the key advantages it had over Microsoft's debuggers is that it enabled single machine debugging, rather than requiring a second machine to be connected over a serial port.
