HI, I can change the Reg value for the current mouse cursor by $NewCursor = "hmove.cur" $UrsprungArrow = RegRead("HKEY_CURRENT_USER\Control Panel\Cursors", "Arrow") $StringArray = StringSplit($UrsprungArrow, "\") $Path = StringTrimRight($UrsprungArrow, StringLen($StringArray[$StringArray[0]])) RegWrite("HKEY_CURRENT_USER\Control Panel\Cursors", "Arrow", "REG_EXPAND_SZ", $Path & $NewCursor) The regValue will change correctly, but how to activate? I have to say : Hey Windows
