billgates: I did a clean install. If you do attempt the upgrade, you will need to re-install all the apps again.
nathan: indeed, but this was clearly communicated when downloading the Windows 8.1 Public Preview
I can be back up and running on a new blank machine in about 10-15 mins, including Win8.1 RTM installed and various key apps installed too, Office, Visual Studio etc and then my settings, files/documents and Windows Store apps come back down by SkyDrive
nathan: Upgrading preview to final will need apps reinstalled, upgrading 8.0 to 8.1 and your apps are all fine
nathan: Just be aware that's unsupported if care about things like that :)

I can't recall the last time I called MS Support :)
nathan: Free installation and security update support in NZ for consumers
