I am not able to disable windows auto update via registry in 2019 Windows server

Question

Hi Experts,

I am not able to disable windows auto update via registry in 2019 Windows server. I have followed official Microsoft page and added the NoAutoUpdate (REG_DWORD) and made the REG_DWORD value as 1 to disable automatic updates in the below mentioned registry path.
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

But I am getting below error.

Note: Hence our environment doesn't deployed with Active directory we cant make the required changes in GPO, So we are trying to disable the windows auto update via registry.

Please someone help me to fix this issue. I am looking forward to hearing from you

Answer 1

Hello,

According to your description and the information in the link, if the AUOptions (REG_DWORD) has been selected 3. It will be download update auto but not install. Try to change to 1.

Meanwhile, you could try to disable Windows Update service to disable Windows Update function.
