Windows 8 and Windows XP
Finally.. I find time to download Windows 8 Preview. Going to install it tomorrow and hope to see it work. Will provide feedback, of course (if it's not reported yet). If you haven't download it and wish to try, get it at MSDN.
Are you using Windows XP? Get the Windows XP End Of Support Countdown Gadget. Today, I have it installed as a sidebar gadget. XP users still have many months to use XP :) If your PC is still OK, keep using it but ensure it's up-to-date with available security fixes. If you want a new PC, get Windows 7 or wait for Windows 8.
