Aug article updated on Jan 13: How to manage Windows 10 notification and upgrade options https://support.microsoft.com/en-us/kb/3080351
Has Micro$oft decided to be helpful...? Or, maybe... has it been embarrassed by GWX Control Panel?
In short, the article provides info (except item 4) that was provided months ago in the thread and elsewhere:
1). "manage the Windows 10 upgrade" a). Automatically by installing KB3035583 and (KB3065987 / KB3065988)
b). Stopping it via
- Group Policy: "Turn off the upgrade to the latest version of Windows through Windows Update."
- Registry: "HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate" | DWORD value: DisableOSUpgrade = 1
2). "Hide the Get Windows 10 app" a). Automatically done on Enterprise/RT/Embedded editions of Windows 7/8/8.1
b). Suppressing it via registry: "HKLM\Software\Policies\Microsoft\Windows\Gwx" | DWORD value: DisableGwx = 1
3). "Enable the Get Windows 10 app." Instructions include creation of a scheduled Task to
- "determine whether your device meets all the prerequisites" (checks for installation of KB3035583 and (KB3065987 / KB3065988),
- "and then it will turn on the Get Windows 10 app as appropriate." (deletes "DisableGwx” registry key)
4). "How to bypass the Unattend screen in Windows 8.1 Update" that runs when KB3065988 is installed:Instructions given for modifying the "Unattend.xml file" that causes the system prompts users to reserve a copy of Windows 10 as part of the OOBE process that occurs at the first startup cycle."
