We have Windows 7 Pro devices and we want to upgrade those devices to
Windows 10 Education version by upgrading those devices and not pushing new

At reboot, after the 100% upgrade, Windows 10 screen is flickering just
before logon if ZCM agent is installed. We uninstalled ZCM agent and do the
upgrade again and everything works fine.

Does someone have or had this issue and if yes, how did you resolved it
without uninstall/reinstall ZCM agent ?

Thanks for help.
