TLB gets removed from the Taskbar

Almost every time I restart Explorer (not Windows OS) for some specific tasks, TLB gets removed from the Taskbar and I have to re-add it again.

How do you restart explorer?

BTW, do you have language bar on the taskbar?

To restart Explorer I use a script

Code:

TASKKILL /F /IM explorer.exe
start explorer.exe

No language bar. Just basic toolbar (folders) with shortcuts to my Apps.

Does TLB appears on the taskbar after Windows restart?

BTW. There is "legal" way to exit explorer without killing it. Hold down CTRL+SHIFT and right-click the taskbar, you'll see the "Exit explorer" menu item.

No I have to add it again.
