Played with this today:

cd\

cd \Program Files\Ccleaner\

copy ccleaner.exe C:\

copy lang-1033.dll C:\

cd\

start /wait /min ccleaner.exe

rem I would like to execute an alt+R keypress here to activate the Ccleaner 'Run Cleaner' button but don't know how

pause 'press any key'

del C:\ccleaner.exe

del C:\lang-1033.dll
