Hide/Show Screen orientation icon
 

Hide/Show Screen orientation icon:

If you wish to hide the Screen orientation icon, shown in the task bar on some devices, you can set:
HKLM\System\GDI\Rotation\HideOrientationUI = 1 (DWORD decimal)
And to show it again:
HKLM\System\GDI\Rotation\HideOrientationUI = 0 (DWORD decimal)

If this doesn't work, you can try:
HKLM\Services\screenrotate = 0 (DWORD decimal)
And to show it again:
HKLM\Services\screenrotate = 1 (DWORD decimal)

Note that this icon and its feature may not be available on your device at all.

Do you know how to make the screen horizontal view? instead of vertical? I know it can become horizontal but how to permanently make it horizontal.???
