Hi @DonghyunK, try to terminate the frozen Windows and then launch the virtual machine and check how it goes. Refer to this article. Also, let us know at what percentage Parallels Tools hangs while installing?
Hi @EKayeW, you are welcome. It can happen due to various other reasons like Windows updates, Windows services not running etc. Also reinstall Parallels Tools to update the drivers, refer to this article.
Hi @EKayeW, please stop the virtual machine by clicking on Actions (From the Apple menu bar) > Stop. Then try to start the virtual machine and check how it goes.
