Microsoft changed many features with Windows 8, one of those many features is how a Restore, Reset and Recovery are done. I personally am very happy with the new feature in Windows 8. To use any of the methods; Restore, Reset, Recover you must first ensure you’ve created a backup DVD or USB image.
When Resetting your PC Microsoft now provides you with the option to reset the Windows Drive (AKA the OS Drive) or All Drives.
This is an extremely useful option because many intermediate to advanced users may run their Windows on one drive and store data on secondary drives (other physical drives). By storing data on separate drives a user can Reset or Recover Windows without losing data.
Moving along, another great feature when Resetting your Windows 8 PC is that Microsoft now provides the option to “Fully clean the drive” (erases all data) or “Just remove my files” (erases your data however in some cases can still be recovered).
I like this feature because it comes in handy when someone may be selling or giving away a computer. “Fully clean the drive” means that Microsoft will apply a more thorough hard drive wipe (format), some call it a low level format. This makes it more difficult for people to recover data from a hard drive. Ultimately protecting the end-user should someone attempt to recovery data.
The full clean option also helps in situations where your computer may be experiencing problems. In rare occasions I have had to format (Fully clean the drive) the hard drive to re-install Windows, again this is very rare as sometimes a quick format doesn’t put the drive into a state in which Windows will install.
