Windows With Windows Vista nearing its first release candidate in preparation for a final launch early next year, Microsoft is providing more details about possible upgrade paths. Of note: Windows 2000 cannot be upgraded to Vista. While Windows 2000 Professional customers may purchase a cheaper "upgrade" copy of Microsoft next-generation operating system, Windows Vista must be "clean installed", which means users will need to back up their files and data manually and then copy everything into place. Applications will also need to be re-installed.

Yep you're so right. Actually I thought it was also impossible to upgrade linux. But it really isn't. Debian GNU/Linux has been upgraded continuously without any (serious) flaw here, for five years !

Microsoft has something to learn from them : database managed installations. Whenever an external program (or, in the case of Windows, also an internal Windows component) is installed, a database tracks every file related to that package. Also library dependancies (in the case of windows, DLLs). It's such a pity that when you uninstall a program which has shared DLLs there is no way to know if you can remove those DLLs safely without compromising any other installed program.

So in the Windows world, if you're the kind of person that installs/uninstalls/upgrades continuously his/her softwares, you end with an unusable system so quickly ... I was used to that, until I found Debian package management system.

Sorry this is a bit too offtopic
