Windows Update: “Some settings are Managed by your system administrator” [duplicate]

I want to turn off Windows Update on my machine (Windows 7 SP1 x64 Ultimate). However, despite being logged in as an admin, Windows update complains " “Some settings are Managed by your system administrator". How can turn off Windows update?

Solution 1:

I fixed the issue by running the following .reg:

Windows Registry Editor Version 5.00

[-HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\WindowsUpdate]

[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\WindowsUpdate]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\WindowsUpdate]
