I think the answer is obvious: don't use Win 10. Go back to Win 7.
After Effects CC 2015 and CC 2014 are supported on Windows 10. Something is awry. Have you uninstalled and reinstalled yet?
Yikes!! I did a standing upgrade to windows10 pro and had zero issues whatsoever. Try re-installing like it said. If you cannot fix this try rolling back to 7. In the Settings>Updates& Security>Recover is an option to roll back to your previous version of WIndows....as long as you did not delete the recovery files after updating. But like I said...I had no problems with the update...like Szalam said, something is awry.
