Windows 8 Apple Photostream沒有同步

因為不明原因，PhotoSteam無法跟 Windows 同步，解決方式如下:

1. Kill these processes:
   ApplePhotoStreams.exe , ApplePhotoStreamDownloader.exe , APSDaemon.exe , iCloudServices.exe, iCloud.exe
2. Delete this folder:
   %AppData%\Apple Computer\MediaStream
3. Launch iCloud Control Panel. You will notice that Photos is not sync. Enable it and apply it.
