Sorry that you're unable to access the Help menu in Photoshop Elements on your computer running Windows 10.
Would you mind trying a quick method of restoring preferences:
Do one of the following:
Press and hold Alt+Control+Shift (Mac: Option+Command+Shift) immediately after Photoshop Elements begins launching. Click Yes to delete the Adobe Photoshop Elements settings file.
Go to Edit > Preferences (Mac: Photoshop Elements > Preferences > General), click the Reset Preferences on next launch button, and then click OK. When you restart Adobe Photoshop Elements, all preferences are reset to default settings.
Thanks for getting back to me. I followed your instructions. The reset preferences button is named Restore default settings on my system. It did not change anything, however, when I restarted Elements.
