These are some of the unique features of Windows 8
1. File copy dialogue
In an effort to create more transparency, Microsoft implemented an improved copy, move, rename and delete dialog that doesn’t just show the progress of each operation, but also a throughput graph and the ability to actually pause individual copy operations. When there’s a problem with a file operation, Windows 8 doesn’t just stop the entire process but keeps these problems in the error queue.
2. ISO mounting
In Windows 8, Microsoft introduces mount ISO files. Once mounted, a new drive letter appears in Windows Explorer that represents the virtual CD/DVD ROM. This lets users finally get rid of annoying third-party tools such as Daemon Tools, Power ISO or Virtual CloneDrive.
3. Windows To Go
Windows To Go allows (enterprise) users to create a bootable Windows 8 environment on a USB 2.0/3.0 flash drive. It even supports unplugging the drive, which causes the OS to freeze momentarily until you plug the Windows To Go stick back in.
4. The Metro UI
When you use the Metro UI for the first time, you’ll see that it’s a very unique way of working with a device. In an effort to create more transparency, Microsoft implemented an improved copy, move, rename and delete dialog that doesn’t just show the progress of each operation, but also a throughput graph and the ability to actually pause individual copy operations.
5. Native support for USB 3.0
The new native USB 3.0 devices work pretty well with Windows 7 already since hardware manufacturers provide their own drivers which is an industry standard.
6. Cloud integration
Windows 8 lets you sync data with the cloud. Windows 8 is going to tightly integrate with SkyDrive’s 25 GB online storage, which is not just for photos or music, but also allows for hosting your user account (personal settings, backgrounds, some data…) for you to log in from anywhere.
The newly introduced ReFS (Resilient File System, code named Protogon) is Microsoft’s next-generation file system. It will first debut in Windows Server 8, but client adoption is well underway.
