For those still struggling with the feature upgrade process using our content, we did include a change to our reboot detection logic in 9.5.12 that should prevent a duplicate reboot from being triggered by BigFix. This has made the upgrade successful for some specific scenarios we were able to pinpoint. The fix is for APAR IJ13194 - THE ACTION TO UPGRADE WINDOWS 10 VERSION MAY FAIL AFTER THE REBOOT. BigFix 9.5 Patch 12 is now available
If you’re able to test out this version in your environment, please let us know if it fixes things for you.
