It should be part of the OS at release. No reason Microsoft can't make it part of the OS. We want, just do it. Apologies if this sounds like a demand or else to thing its not Ill be in line for Windows 7 release, but I just want to make it short and simple. Im tired of the stop gap measures of going through third parties providers for a solution for mounting ISOs and the VHD mounting shows how easy life can be with these virtual partitions standards are built into the OS. So, do with this thread what you will but I put this Windows fan down for believing that ISO mounting should be part of this new OS.ChuckBuc
