Background: I have a mid-2012 MBA which is running MacOS 10.12.4 as the native OS and Windows 10 Pro as the guest OS. I have already tried solving the below described problem by i) the restarting my MBA and ii) uninstalling and re-installing Parallel Tools, neither of which had any impact. Problem: If "add" (create / paste / save / etc.) a file to the MacOS Desktop it i) does not appear on the Windows 10 Desktop but ii) it does appear in File Explorer / Desktop (i.e. the added file is being saved on the Windows 10 Desktop but cannot be seen on the Windows 10 Desktop). If I add a file to the Windows 10 desktop it i) does appear on the MacOs Desktop band ii) it does appear in Finder / Desktop. I will also note that I confirm that Parallels has been setup to share the desktop between MacOS and Windows 10. Observation: If I change the resolution of the Windows 10 virtual machine (i.e. to 1280 x 800 and then back to 1440 x 900 [i.e. its native and original / start-up resolution] then the file which was originally added to the MacOS Desktop but could not been seen on the Windows 10 Desktop becomes visible on the Windows 10 Desktop. Ask: Please provide a solution to this problem as it is making working on both the MacOS and Windows 10 environments at the same time very difficult. Thanks in advance.
