Win10 old popup has reset the application default settings solution

        
After an emergency investigation, it is now possible to confirm that the Win10 system that appeared before is "痉挛"; the problem is caused by the installation of the cumulative update KB3135173. Combined with the user's feedback in the comment area, the reason for inferring this problem is that Microsoft has arranged an imperfect mechanism to reset the system default application after each installation of the cumulative update.
Microsoft has a bug in the default app reset mechanism. Because the system conditions of each user are different, the third-party programs that cause this problem also have their own advantages. When the problem occurs, "痉挛" may be due to Win10's failure to reset the default application, resulting in an infinite loop "can't stop".
Users with similar problems can uninstall KB3135173 first, or the latest installed cumulative update that caused the problem (for users who have not installed KB3135173), “flash screen痉挛” after the problem is solved, can be "quietly" Uninstall the relevant third-party application, then try to install the update patch again, and continue to install the temporarily uninstalled third-party application if there is no problem. If you have a better solution, please feel free to exchange in the comment area.
