Say NO to Windows 10!

Steve Gibson over at GRC has created a simple and easy tool for removing the prompts to update to Windows 10 on non-enterprise installations of Windows. This solution works well for single desktops. Here is the link: https://www.grc.com/never10.htm

For a wider scale deployment of this fix you can use Group Policy Preferences. Here are the settings needed:

  1. Create a new GPO and a new Registry Item (be sure to create this in Computer Configuration, not User Configuration):
    4-7-2016 8-58-49 AM
  2. Here are the settings for the new Registry Item:
    Action: Replace
    Hive: HKEY_LOCAL_MACHINE
    Key Path: SOFTWARE\Policies\Microsoft\Windows\Gwx
    Value name: DisableGwx
    Value type: REG_DWORD
    Value data: 1
    Base: Decimal
    4-7-2016 9-06-35 AM
  3. Create another Registry Item with the same Action and Hive. Use this for the remaining configuration:
    Key Path: SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
    Value Name: DisableOSUpgrade
    Value type: REG_DWORD
    Value data: 1
    Base: Decimal
    4-7-2016 9-28-32 AM
  4. Scope this GPO to the OU that contains the computers that you want to apply the settings to (not to a users OU). Reboot the target PCs and verify in the Registry that the settings are in effect by looking for the two keys:
    4-7-2016 9-39-52 AM
  5. The value data of the “DisableGwx” and “DisableOSUpgrade” DWORDs should both be set to 1:
    4-7-2016 9-41-26 AM
