A chart Microsoft provided to a Wall Street Journal columnist that spells out which versions of Windows and XP can be upgraded to Windows 7 without a cumbersome "clean install" is causing a dust-up between bloggers and prompted Apple users to poke fun at Microsoft's upgrade process.
The chart, which Microsoft provided to Walt Mossberg, who writes the popular "Personal Technology" column in the Wall Street Journal, consists of a 66-cell matrix that details what XP and Vista users face when upgrading to Microsoft's next operating system.
Only 14 of the cells indicate an "in-place" upgrade, one that retains all data and applications, but simply swaps out the OS. Vista Home Premium, for example, can be upgraded in-place only to Windows 7 Home Premium or Windows 7 Ultimate.
The remaining 52 cells show where users must do a "custom" install, also often referred to as a "clean" install. That process requires users to back up data and settings, install Windows 7, then restore the data and re-install all applications.
