When rebooting/logoff from OS i get lot of tray popups where PG probably shows events related to above ...

To fix these i assume i need set
csrss.exe
winlogon.exe
svchost.exe

to Allow Modify & Read + Access to Physical memory

i'm i right?

 

Yes except that logonui does not require access to physical memory And all should be protected from Modification & Termination.
