REM *** Remove Cortana ***
REM Currently MS doesn't allow to uninstall Cortana using the above step claiming it's a required OS component (hah!)
REM We will have to rename the Cortana App folder (add ".bak" to its name), but this can be done only if Cortana is not running.
REM The issue is that when Cortana process (SearchUI) is killed, it respawns very quickly
REM So the following code needs to be quick (and it is) so we can manage to rename the folder
taskkill /F /IM SearchUI.exe
move "%windir%\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy" "%windir%\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy.bak"
