I got the script to work after installing version 17 of CherryPy,but unfortunately, when I went to http://(myPiIPaddress):5050 and tried to authorise, it failed, with the message:

My Winsxs folder is 12GB in size and contains nearly 20,000 subfolders and over 74,000 files. I’ve just run Windows Update Cleanup and it has removed a few hundred MB. Can this folder be further reduced safely?
