Greetings All, We have just tested ISR with Vista 32/64 and the latest SP1. So far, Vista 32 has no issues and is working very well. Although the ISR technology is not officially supported by Vista 64, one is able to make static snapshots/archives by booting a Windows 2000, XP, or Vista 32 snapshot to make the copy. This was the case with the early SP1. The RTM Vista 64 SP1 is not as forgiving. It has changed a few aspects of NTFS file security thus the above method will not work. Again, this is only for Vista 64 SP1. In my very loaded Engineering queue is the eventual full compatibility with Vista 64. I am curious as to how many folks are using Vista 64? If this is large number, I will raise the priority of this task. Although, raising the priority does not mean it will be out next week, but it does quicken the delivery.
