^^^ Yup, that's the way that Microsoft seems to work, Fender62. They take a basically sound product and then 'improve' it in such a way that it makes it more difficult to use.
For example, users of Microsoft Word could easily find their way around it with a toolbar with 'File', 'Edit' 'View' etc on it, both because it was fairly intuitive and also because it matched what they saw in other software (both from Microsoft and from third parties), such as web browsers and DTP programs. Then someone came up with the 'wonderful' idea of using 'ribbons', which makes everything far less intuitive for users.
Similarly, with each update of Word, they've made it far harder to find the controls to turn off features such as automatic paragraph numbering, which should never have been turned on (in the default configuration) in the first place.
As you suggest, their operating systems seem to work along the same lines. i.e. 'let's find something that's already working well and then 'improve' it. That resulted in Windows 7 being 'improved' to produce Windows 8, which (in its early versions) removed the easy-to-use Start button from user's screens but failed to replace it with anything anywhere near as simple to use.
Windows 10 is, admittedly, a big improvement on Windows 8, but once again Microsoft has assumed that everyone wants to do things the way that their design staff have decided is 'best', even though that actually boils down to making simple tasks far more complicated!
The reason is obvious when you think about it though. If a company puts many thousands of staff on full-time contracts to 'improve' things, they're hardly going to risk losing their jobs by saying "it's fine as it is, actually" are they?
