My boss upgraded me to a27 inch iMac Retina a few weeks ago, I have installed Parallells 12.0.2 (41353) and installed Win10 from DVD. The first few weeks I had no problems with any functionality of Win10. However the last few days "explorer.exe" appears to crash and then immediately reload when I right click on files to open through the context menu whether it be within the Win10 VM or back on OSX. It appears to work for hours at a time without any problems, and then crashes. The next time it may work for only half an hour or so, and then crash. I can't attribute it to any one particular file type, and I don't recall any recent updates that may cause it. Has anyone experienced similar? Workarounds?
