IsoImages : additional virtual drive software required such as: Power Iso, Alcohol 120%, Daemon Tools etc. No. of virtual drives is limited according to the software used.	Windows 8 itself has inbuilt ability that allows you to create a virtual drive to mount the ISO image so that you can easily use it just like a normal DVD. No. of virtual drives not limited.
Antivirus Required	Built-in Antivirus (bad news for hackers): Windows 8 has an antivirus present inside the kernel of the operating system. This means that your system won’t boot if a corrupt USB device is plugged in. It sounds impressive though we yet don’t know whether it would pass the test of time…. & viruses!
PDF files: additional PDF reader is required such as: Foxit Reader, Adobe Reader etc.	Reader App: inbuilt capability to read PDF files.
Browser: IE8 (upgradable to 9) or IE9	2 Separate browsers IE9 & futuristic IE10

Enhanced multiple monitors support:Microsoft has announced that users can now separately use morethan one monitor to connect withWin 8operating system running on a single PC. Win 8’s PCmanagement allows user to use multiple monitors atsame time with allowing the flexibility offered never before by allowingstart screen at one monitor & desktop in another.

One can also choose taskbar onboth screens having different icons oneach monitor; it is just like having 2 different PC’s.Moreover, you can play with wallpapersalso bychanging them separate on each monitor.Such support isn’t there inwin 7.

The settings areahascontextual apps likevolume, brightness, restart&shutdown buttons. We canalso share stuffs, links & contacts etc. as Hotmail, Gmail, Facebook & Twitter support also has been provided but limited only.& on other side, win 7 is missingall these cool social networking features.

All in all, I do expect Windows 8 to be a serious upgrade on Windows 7 and with Microsoft working on the things that require some tweaking; I genuinely believe that Microsoft is finally ready to launch an OS which will take the world by storm.
