If you are still running a Beta, RC1 orRC2 version of Windows Vista, hit the panic button and upgrade to the full version within the next few weeks.
Microsoft has warned that:
"After May 31, 2007, users that 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. The opportunity to log in normally for these 2 hour sessions will only be available for a limited time."
Unless you can handle major work disruption and the loss of data, you will need to install the final version of Windows Vista or get the Windows Vista upgrade ASAP.
