Apple has always been very much theirs when it comes to offering compatibility with other operating systems, whether mobile or desktop. Luckily over the years, it has stopped being so exclusive and has started to use more compatible formats y no solo exclusivos que nunca lleguen a otro lugar que no be el detrimento del Username.
A few years ago, before the arrival of Windows 10, we were forced to continually install codecs to be able to watch movies or basically videos not compatible with our version of Windows. Luckily, with the arrival of Windows 10 that is over and you do not need to install practically any codecs to be able to enjoy any video.
In 2016, Apple announced that it would stop developing QuickTime for Windows. Apparently the company TrendMicro detected a serious security problem in this application for Windows in 2016 and instead of fixing it, it left the application totally abandoned. With the arrival of Windows 10, continuing to maintain a version of QuickTime, whose only function is to play videos, did not make sense, since this version of Windows supports all video formats, so it did not make sense to develop QuickTime.

In this way, if you need to download QuickTime, la última versión disponible es la que podemos hallar en la Web de Apple, a version that is compatible with Windows 7. But that version has the security hole that I mentioned in the previous paragraph, so there is no point in installing it to endanger our equipment.
Si tiene que reproducir contents que solo es compatible con ese formato, the best option is to resort to the VLC player, a free player that is fully compatible with all formats on the market.
