The TIP (tablet input panel) toolbar takes up a lot of space on the taskbar, which you may want to free up. doesn't appear there's a user setting for it.
If you want to remove the button, you can do so as follows & reboot :
regsvr32 /u "c:\program files\common files\microsoft shared\ink\tipband.dll"
To undo your changes & restore the TIP button permanently :
regsvr32 "c:\program files\common files\microsoft shared\ink\tipband.dll"
