windows 10 quicktime player wont load

Apparently you do not have a running version of QuickTime Player there, from which you can access its menu.

Lets take a few steps back. QuickTime Player 7 was for Windows 2000, XP, Vista and 7. It was never for Windows 8, 8.1, or 10. Apple stopped developing QuickTime for Windows in 2015, and advises users to uninstall it. About QuickTime 7.7.9 for Windows - Apple Support

1. You probably don’t need it.
2. If you are going to install it against advise, you will have to perform some tricks on later Windows versions. There are other websites that describe this in detail.
3. If this is about other software suggesting to install QuickTime for its own codec support, then you can install just the “Essentials”, without the Player software. You will still need to do a trick by not using the regular installer, but do a custom install. There are other websites that describe this in detail.

Go to Preferences﹥General and turn off ‘Show Content Guide automatically’. That feature tries to connect to a server that is now long offline.

Excuse me for the Mac centric description. It may be a bit differently worded for the Windows version:

Edit menu﹥Preferences﹥Player Preferences﹥uncheck: Show Content Guide at start up
