    Don’t believe Microsoft. They worded their instructions badly. You WILL loose ALL software that you installed to your desktop!! Regardless of what options you select.

    MS meant to say that apps downloaded by the OS or by you from the Store will be retained but that DOES NOT MEAN any software proper.
