like everyone else... I am in the same boat with AMDS pushing my CPU usage to 100%, even when iTunes is not in use or open!
followed by:
iPhone fails to backup... just stalls after 2 minutes, and is no longer recognized when connected to iTunes
iTunes store is just a blank page, even when I login.
and I tried all the fixes: removing all Apple software in order, uninstall, re-install, deleting the library.xml file and a few other I found online, and nothing f'n works!
since this started in July, and at this point, I just give up on Apple products and going to look into Android for mobile device. Apple couldn't give 2 sh%ts about Window users which is more than obvious.
