Alternatively, you could just leave the policy setting configured and do the ADMX upgrade and just live with the “Extra Registry Settings” message in GPMC (See below).
Note: This policy will still apply with the “Extra Registry Settings” will still apply to the Windows 10 1511 build.
If you already have a Central Store in SYSVOL on the domain controller, skip to the copying files section below.
The Central Store is a file location that is checked by the Group Policy tools.
However, with the release of Windows 10 1607 the Group Policy setting “Defer Upgrade and Updates” has been completely removed and replaced by new policy settings under “Windows Update Defer Windows Updates” (see below).
The two new policy settings called “Select when Feature Update are received” and “Select when Quality Update are received” (see below).
Windows Server 2012 Group Policy Management Console (GPMC) has a new feature that allows administrators to remotely force a Group Policy refresh on all computers in an Active Directory (AD) Organizational Unit (OU).
The files that are in the Central Store are later replicated to all domain controllers in the domain.
In addition to the above search, you can also search for a Microsoft Excel spreadsheet which highlights the changes in GPO’s for that platform, for example search for the following phrase: Once you’ve found the corresponding templates for the version of Windows 10 you want to support (for example here are the ADMX templates for Windows 10 1511) then download the MSI (or copy it) to the desktop of your source computer.
Double click on it to start the installation (extraction) accept the EULA and then let it extract the files to the default location which is something like C:\Program Files (x86)\Microsoft Group Policy\Windows 10 Version 1511\ close the wizard when done.
NOTE: Some times when Microsoft release a new OS they might rename the GPO setting but still keep the underlying Registry Key the same.
This means that the name of the policy setting has changed but the actually setting is preserved when upgrading. Therefore, you might want to go back to your ADMX Group Policy Central store de-configure the “Defer Upgrades and Update” GPO setting before upgrade the policy files.
That’s it, any computers that are present in the OU targeted by the GPO will get the new setting and will apply the changes if appropriate.
