Until Apple decides to accept responsibility and fix this issue you will need to get rid of iCloud. It's too bad because before Apple decided to throw out the patch/malware, it actually worked kind of neat. So, this is what I've done to regain control over Outlook and iTunes; re-boot the pc, launch iCloud control panel and sign out, saving data to your computer when asked. Under add/remove programs, un-install iCloud, re-boot again. Go to windows control panel under folder option, second tab (view) select "show hidden files, folders & drives" and select ok. Now double click on your "C" drive and do a "Control F" (for find). In the search box type APSDaemon.exe and hit search. Right click on this file and hit Delete sending it to your recycle bin. You may want to cut this file out of your recycle bin and place it in a temp folder until you are sure everything is working properly. You should now be able to use Outlook and iTunes without them hanging. In Outlook, under contacts you will need to move your contacts from iCloud contacts back to your default contacts folder. Under iCloud contacts do a "Control A" and drag your contacts back to their default location.
Hope this helps, in the future I will be vary leery of installing anymore Apple patches.
I am a PC and Apple trashed me!
