Microsoft makes "Mind Maps Pro," but it's only for Xbox, Windows 10 version 17134.0 or higher (https://www.microsoft.com/en-us/p/mind-maps-pro/9mwz4wtswwp5?SilentAuth=1&wa=wsignin1.0&activetab=pivot:overviewtab)
Some of the reviews found by this search (https://www.google.com/search?q=mind+mapping+software) suggest that you can use Microsoft Visio (a component of Microsoft Office) for mind mapping. If you're still using Windows 7, Office 2016 is the newest version that you can use. Although Visio 2016 is quite expensive from Amazon (Microsoft no longer sells this version), if you look around, you can probably find copies at a more reasonable price -- assuming that you want to use Visio.
