Windows 8 to Support Native ISO and VHD Mounting
Mount those ISOs in Windows 8 without any additional tools.
Many of you have likely handled disc image files or even virtual hard drives. Sometimes there's no need to burn a DVD if you already have the disc image on your hard drive. While there is third-party software that will quickly and conveniently mount a disc image so that it appears as a DVD drive, such functionality will be baked into Windows 8.
Rajeev Nagar, principal group program manager for Windows, detailed Windows 8's built-in ISO and VHD mounting support.
"So how does this work in Windows 8? It’s quite simple – just 'mount' the ISO file (you can select mount from the enhanced Explorer ribbon or double-click or right-click on the file), and a new drive letter appears, indicating that the contents are now readily accessible," he wrote. "Underneath the covers, Windows seamlessly creates a 'virtual' CDROM or DVD drive for you on-the-fly so you can access your data."
Windows 8 will also support mounting of virtual drives.
"The Virtual Hard Disk (VHD) format is a publicly-available image format specification that allows encapsulation of the hard disk into an individual file for use by the operating system as a virtual disk in all the same ways physical hard disks are used," Nagar explained. "VHDs are handy for portability of system settings or to play back what has been saved as a snapshot of a system."
"Accessing a VHD in Windows 8 is as simple as what we’ve done with ISO files, but there is one important difference: rather than appearing as a removable drive (as is the case with ISO), VHDs appear as new hard drives," wrote Nagar.

lol windows XP fail, thats like saying yeah I think im gonna stick with my windows 3.1 till something with less of a footprint comes out.
Skipping over Windows 7 might be a good idea for anyone who is happy with windows XP, seems to me there will be many new and useful features in Windows 8
Personally, I am done with windows XP...
The problem is that pretty much all of your other formats are not formalized standards in any way.
o no, it couldn't be that someone just doesn't like windows vista or 7, and it sure isnt the fact that xp still runs perfectly fine.
i have more problems with the 2 win 7 pcs than my xp machine that hasn't been formated in 2-3 years and survived 6 hard drive failures.
i'm hoping that with win 8, ms addresses all my complaints, but we all know that will never happen.
BIN/CUE and IMG files are treated the same as ISO by Microsoft. All of their existing tools work just fine with them. If you really think some other proprietary image format is important and needs recognition, you're delusional.
