So if you want to Disable System Tray in Windows 7 (valid for users also Vista), open Registry Editor without fear and attacked. :) Tut regedit.exe in Searchthe from Start Menu And follow the path HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorer. In the right panel create the entrance DWORD (32-bit) NoTrayItemsDisplay And give it the value 1 (1=enable; 0=disable).
Then give Logoff/Logon for the modification to have an effect.
If you are subsequently merciful to the clock Remaining alone and left in the corner of the monitor and changing your system, then you only have to follow the same steps until NoTrayItemsDisplay and delete this entry or to Change the value in 0. The clock will please: p.
Use: Even if you send System Tray for a walk, applications that usually run in it will not be deactivated, but only hidden. To disable them, disperse them from the startup (run->msconfig->startup).
