See attached graphic that illustrates our problem clearly.
- PROBLEM: After Windows Update, all existing users lose functionality of some Taskbar items (Start, Action Center, Date/Time). When clicked, nothing happens. Microsoft says user profiles not present during Windows Update fail to get updated, causing %Appdata% and TileDataLayer components to not match expected values for updated OS. This explains why brand new user profiles work fine in the updated OS, while older profiles don't.
- ENVIRONMENT SUMMARY: VMware Horizon 7.1 with Floating Pool, AppVolumes, UEM, Group Policies, Local Policies and Windows 10 Enterprise (CBB) v.1607.
- TROUBLESHOOTING: Fixing the root cause will NOT reverse the damage done to profiles, so whenever we troubleshoot, we need to wipe our writable volumes and start from scratch logging into a fresh, non-customized, older version of the OS. After profile is created from the OS, we perform a Windows Update on the Golden Image, then recompose, then try logging existing profiles into the updated OS. If existing profile Tasbar features work after this, then we conclude the problem has been resolved (which is what we thought in June, but it came back after July updates). Also, not all updates break the Taskbar features; we went months without issue earlier this Spring. It seems that once any customization/optimization is done, irreversible damage takes place leaving profile that log in vulnerable to breaking during some windows update in the future. Therefore, we tested not applying any customization; especially the VMware optimization tool. This corrected the problem, therefore allowing us to successfully update the June MS patch that previously broke profiles, but here we are again with broken taskbars after the July MS Windows Updates of the same Windows feature release (1607).
