DisableWindowsUpdateAccess registry setting

Hello all,

Range = 1|0

- 1 = Enabled. All Windows Update features are removed. This includes blocking access to the Windows Update website at http://windowsupdate.microsoft.com, from the Windows Update hyperlink on the Start menu, and also on the Tools menu in Internet Explorer. Windows automatic updating is also disabled; you will neither be notified about nor will you receive critical updates from Windows Update. This setting also prevents Device Manager from automatically installing driver updates from the Windows Update website.
- 0 = Disabled or not configured. Users will be able to access the Windows Update website and enable automatic updating to receive notifications and critical updates from Windows Update.

what is the ideal value to set this setting. Everytime when we do update on windows machine it throw error "problem installing updates 0x8024002e"
when we change that to 0 it takes updates.
we get the updates from wsus. wsus shows PC is  up to date. but there are no cumulative updates installed

Any suggestions

Thanks
