hello,

after the upgrade to SEP 12.1 RU3 i have this problem on all win 7 client:

the yellow shield don't appare near the clock on the application bar.

if i setted this (show notify and icon for SEP in notification area icons), after a reboot of the client this setting come lost (show only notify for SEP in notification area icons).
 

you mean it does not show up even when you configure display the client ?

if i setted this (show notify and icon for SEP in notification area icons) the yellow icon appears, but after a reboot of the client this setting come lost (show only notify for SEP in notification area icons) and i cannot see the yellow icon.

can you show the screen shot.

and also check if the client has the same policy as set on the SEPM.

Hello,

Could you check if the "Symantec Management Client" and "Symantec Endpoint Protection" Services are running?

Since this issue is occurying only on Windows 7 machines, then you may try Turning off the UAC, Stop and Disable the Windows Defender services and Restart the client machines.

Secondly, make sure all your policies are locked in SEPM.
