HKCU Registry Value Not Being Applied (Loopback Mode Merge)

    Question

  • Hi,

    We've got a group policy targeted at an OU containing Horizon View virtual machines (Windows 7).  Loopback mode is merge and one of the user preferences is to replace a HKCU registry value (Internet Explorer CacheLimit).

    When a user logs on to the virtual machine, this registry value is not applied.  Running gpresult shows the policy is not being denied though.  But other user preferences to replace HKCU registry value is applied (Internet Explorer ContentLimit) and to set the Internet Explorer Start Page is applied as well.

    While the user is still logged on, running gpupdate manually will see the un-applied registry value being applied.  But once the user logs off, the virtual machine is refreshed and this issue starts all over again during the next user logon.

    So not sure why the policy won't apply at logon but will apply when running gpupdate manually.  Any advice would be most appreciated.

    Thanks.

  • The group policy is configured as required, a user preference setting with loopback mode as its targeting an OU with computer objects.

    Further googling seems to point to an issue on the horizon view front where refreshing linked-clone machines face this issue where group policies may not be applied.  Several workarounds have been put forward by tackling the problem at the parent image before recomposing the machines.

    So looks like GP isn't the problem.

    Thanks.

  • Hi,
    Please share us where you set up preference in GPO under: computer configuration or user configuration?
    Loopback Mode Merge indicates that the user policies defined in the computer's Group Policy objects and the user policies normally applied to the user are combined. If the policy settings conflict, the user policies in the computer's Group Policy objects take precedence over the user's normal policies. Please have a look the details regarding to understand “User Group Policy Loopback Processing Mode:
