Here is how to disable both dynamic ticks and HPET through Command Prompt:
Go to Start, type cmd, right-click on Command Prompt, and press Run as Administrator.
Type bcdedit /set disabledynamictick yes, and press Enter. You’ll get a message saying, “The operation completed successfully.”
Type bcdedit /set useplatformclock true, and press Enter. Again, you’ll see the same message from above if you did it right.
Restart your computer.
