Hi. I think I somewhat have an ultimate but long solution to itunes restore errors like 3194, 4014, 11, "iTunes has stopped working" error etc on windows especially when jailbroken. Things you need  are Regcure pro(a registry cleaner)  or  any other you can get, latest iTunes setup (the very latest at the time you want to follow this method), latest iOS (idownload blog download site recommended) for the device you're receiving error restoring (the very latest version as well), iReb, then follow the steps below:

Step 1; Uninstall iTunes and all apple's installed (e.g. Bonjour, apple mobile support)

   Go to control panel; uninstall all the softwares that say apple.

Step 2; Delete all apple folders from disk  C.

    Go to my computer > disk C > click on "organize" (on windows 8, click "view" and click on "options") > folder and search options  (this opens the "folder options") > click on "view" panel > under "hidden files and folders", select "show hidden files and folders", "apply" and "ok"  > now go into all the folders and delete anything that says apple, then empty your recycle bin.

Step 3; Go to  search and type "regedit".

        Open "regedit" > HKEY_CURRENT_USER > "software" and delete any folder that says apple.

Step 4; Use a registry cleaner app (e.g Regcure pro).

            Use the application to scan and clean registry on your computer

Step 5; Restart your computer

Step 6; Now search and   open "disk defragmenter"  or use the one in the Regcure pro app ,  defragment disk C and restart your computer one more time.

Step 7;  Now install iTunes  and wait for it to finish installing.

Step 8;  put your device in dfu mode using iReb.

Step 9;  Open up iTunes ; it will detect your device in dfu and says" device must be restored" (make sure you're connected to a  working internet before this step).  Press "shift" on your keyboard and  click "restore" then select the latest iOS you downloaded. iTunes should restore your device without any error  if you follow the exact instructions above.

this should help you guys out there hopefully. Best of luck
