What do you get for the following?

    import os
    windir = os.environ['SystemRoot']
    more_path = os.path.join(windir, 'System32', 'more.com')
    print(os.path.exists(more_path))

If more.com doesn't exist, your Windows installation needs to be
repaired. If it does exist, then probably PATHEXT is missing .COM.
Ensure it's listed in the output of the following:

    import os
    print(os.environ['PATHEXT'])
