Windows 8 has been recently announced at Build Windows conference. It has been adapted very warmly and enthusiastically amongst the geek community. However people running different versions of Windows like Windows 7, Vista , XP still wonder if they can install it.
The upgrade path from earlier versions to Windows 8 developer preview is as follow:
| Installing Windows Developer Preview | ||
| Install on: | Windows Developer Preview with developer tools | Windows Developer Preview without developer tools |
| Windows 7 | Clean install only | You can keep accounts, files, and settings |
| Windows Vista | Clean install only | You can keep accounts, files, and settings |
| Windows XP | Clean install only | You can keep accounts and files |
| A clean install is supported on all builds. You will only receive the full set of installation options when setup is launched in Windows. | ||
Migration of applications is not allowed with the release of Windows Developer Preview, but other options are available to keep your accounts, files & settings in Windows.
Also note that you can’t uninstall the Windows Developer Preview.
To reinstall your previous operating system, you must have to restore or use installation media again.
