Hi Steve,
There are only two real solutions:
1) Use a third party boot manager like BootIT NG that can hide each OS's
installation volume from the other when booted.
2) Run Vista Ultimate and install and use Bitlocker.
If XP can access the Vista volume in any way, it will destroy the restore
points regardless of whether or not System Restore is running.
