Microsoft's market size is built around legacy, IT, and PC Gaming. Yet I know people in IT that will not run Microsoft at home, just in a corporate environment. Stock does not equate to quality product. Microsoft is trillion dollar company that makes some of the worst User Experience products.
I find the user experience with Microsoft products to be bad. They continually have inconsistencies with their shortcut key bindings. Example would be Ctrl+F, find something but in Outlook it forwards and email. Visual Studio has numerous bad user experiences that they choose not to fix. Example is you cannot stash individual files in GIT, it is all or nothing. Only way around is GIT via terminal environment. It is 2025 and Visual Studio still cannot display source code in Vertical and Horizontal at the same time, one or the other. VSCode has had this feature forever. You have to pay me to use Microsoft software.
I don't need to use spreadsheets so Excel has no value to me. If a spreadsheet is needed, it is the most basic and LibreOffice works just fine. Only reason I use Outlook is because of IT. I don't even use Word and use MarkDown with PDF generators, plain text, or LaTex for documentation.
Microsoft had to universally disable Registry backups via a Windows 10 Update because they sold Surface laptops with low storage. Registry backups where filling up the hard-drive. These are the ones trying to compete against Google's Chromebooks.
WINE / Proton is displacing Windows in the PC gaming market. It actually gives users a better experience in some instances. Example would be that shaders can be compiled without running the game. Windows Direct X implementation will only compile shaders while the game is running. This will lower the FPS and has known to cause stuttering during first play through.
I will never install Windows OS on any of my computers ever again. The OS keeps getting worse and worse with newer versions. I've reached a point where if I need Windows OS the game / software is not desired and no money will change hands. I also will no longer buy a desktop or laptop that forces Windows to be purchased too. If there is ever a reason I need Window it will be installed as a VM.
The only application from Microsoft I will most likely use is VSCode and I'm trying to replace it with Zed and other tooling.
There is no argument people don't use Microsoft. The argument is the products coming out of Microsoft are low quality. Still waiting on Azure's feature to delete a GIT pull request in case sensitive information was accidentally pushed to the repository [0]. Microsoft truly does not respect the end user. You can see this with their forced bloat-ware such as Cortana, XBox features, and Recall, and user request never ending request to remove these useless / unused features.
Don't worry, their stock will go up as they push more advertisements onto the desktop for Home users. Investors love such trash.
