On May 18, pre-release versions of Windows Vista (Beta 2, RC1 or RC2) will begin prompting users with warning notifications about the upcoming expiration on May 31. It is therefore recommended to backup all data and move to a final version of Windows before the expiration date. Between June 1 and August 28, customers who continue to use pre-release versions of Windows Vista will be able to log in for 2-hour sessions to retrieve data. After 2 hours of use, the PC will automatically reboot without providing the opportunity to save data.
If the user would like to switch editions of Vista, the appropriate upgrade version must be purchased and a clean installation needs to be performed. Customer Preview Program participants will not be receiving discounts, other than the option to purchase upgrade versions of Windows Vista, as opposed to the full versions. As already noted previously, performing a roll back to Windows XP is not possible.

Oh well, it's not like I'm actually running them... but still...
have done the sensible thing, and have had your PC set up to dual boot with Windows XP on a main HDD
or partition, and put the Windows Vista test build on a seconary HDD or partition ... right?
That way, you haven't lost your original OS, and you don't face having to completely reprogram your PC.
I think *most* testers use VMWare (or similar) and install the product into a Virtual Environment so as not to screw up their original OS.
But, from reading the above, it seems that some people are silly enough to install a non-RTM candidate as their primary OS. Geesh.
