New Vista desktop was corrupted by using the Try and Decide function in TI 11 (retail box). I was trying installation of new software in safe zone (Roxio easy Creator 10), but to complete installation needed to reboot, so first hit the Try and Decide "apply" button. Knew from documentation that should not re-boot until "apply" function completed, but computer kept processing for 9 hours and finally I gave up and rebooted - ended up with corruption. Resolved by using TI-11 to restore to latest backup so no permanent damage. Did I do something wrong with Try and Decide (other than give up after 9 hours)? Anyone else have similar problem?
