Photos App not working "Invalid Value For Registry"

It is also very possible that sysprep is screwing this up as well. Either fslogix or sysprep. But here's the update from my tests this morning. I basically could NOT reproduce it because the photo app was in a "working state" from the get go. I don't currenly know of a broken user either.

BUT i tested combinations of having the InstallAppxPackages fslogix reg key set to 0 and 1 and saw no difference in behavior, either deleting the profile container and trying logging in wiht both settings AND keeping the same profile in place and toggling the setting, restarting the fslogix app service each time.

So yeah, inconclusive testing so I can't reliably reproduce this at all.

maybe the latest fslogix build resolved this issue.

Maybe upgrading FSLogix to the latest release, includes the added feature from FSLogix 2210 (2.9.8361.52326) that may include a fix for it. We'll be deploying the latest to production soon and see if it makes any difference.

Feature: Added a new process during the sign out phase, which creates an AppX package manifest for the user. This manifest is used at sign-in to re-register the AppX applications for an improved user experience. This work is on-going as AppX packages and applications continue to evolve. The focus for this work has been on the built-in Windows apps (inbox apps).
