Moving To Windows 7?

Windows 7 has RTMed & will be available through various sources starting from August 6th, not to mention that the particular build 7600.16385.090713-1255 has been available on torrents for quite some time. If you’re already on a RC (or later) build or are planning to upgrade from Vista, here are some pointers & links that might be helpful. If you’re running Windows Vista Home Premium or Windows Business you’re good to go. Windows 7 will definitely perform better on your machine than Vista.

If you’re uncertain about your PC hardware capabilities for Windows 7, then use Microsoft Windows 7 Upgrade Advisor.

Windows XP to Windows 7 is NOT supported, use Windows Easy Transfer.

You’ll need to do a clean install. However, you can use Windows Easy Transfer to move your files.For XP it needs to be downloaded, Windows 7 has the Easy Transfer wizard built-in.

Window Vista to Windows 7:

To install Windows 7 on 4GB drives: You’ll need to use something like vlite to disable installation of features in Windows 7, create the ISO & use the tool above to make a bootable USB drive. Here’s an article on vlite. Here is an image from Ed Bott that shows the approximate amount of hard disk space taken by the various Windows 7 SKUs:
