Now you want to change them to Unmanaged.

You replaced sylink.xml for Unmanaged SEP Cd1\SEP\Sylink.xml

Still clients are not able to do the liveupdate and the default admin defined Scan runs.

Here is the default Admin Defined Scanand if you have created few more scans for this users it will also be listed in the same location but with a different name.

HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\AV\LocalScans\5df13630-79f7-4c70-002b-16b8952f5533 ( name can be any hexadecimal name )

So you can delete this and then you can create your own scan.

Liveupdate button is greyed out even after replacing sylink.

HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\LiveUpdate

AllowManualLiveUpdate  0- means liveupdate button will be greyed out. 1-means it will be available to click.

In the same place you can enable product updates by changing the value of

EnableProductUpdates  to 1

For Scheduling and Enabling automatic liveupdates.

HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\LiveUpdate\Schedule

Change the value of

Enabled to 1 – for Automatic updates.
