Visual Studio 2008 (Orcas) Beta2 VPCs Expire November 1, 2007
Microsoft has announced that Visual Studio 2008 Beta 2 VPC images will expire on November 1, 2007, rather than March 15, 2008 as was originally announced.
After November1, 2007, you will have 2 hours to backup all your data, but you can reboot and then you will have two hours more. So, it is recommended to backup all your data before November 1, 2007.
