What os are you using?

Windows 10 on an HP Envy 360. Kinda want a Mac still. We will see what the future brings.

I am using windows 10, with out any special edition.
I have installed widgets and it is much better then previous Os. from windows.

Windows 10, Linux Ubuntu and MacOS Mojave depending on the work I am doing. MacOS is the best in terms of performance and UX.

Windows 10 why?

First of all, security. Windows 10 under this system for a really mature system
For a regular user, security is the same as for a company that is harder to store and process user data. Activities that we have necessarily transferred to the network infrastructure - i.e. it is up to you to take care of your own safety. Microsoft in Windows 10 makes it much easier for us and ... if it is not a system of this kind, then nothing bad will happen to us.
The security of Windows 10 is based on two key issues - the presence of the Defender antivirus engine, which turns out to be just as effective as any other packages. Of course, it will not be able to provide us with everything that modern security solutions can do, but for a conscious and important - a prudent computer user will be absolutely enough.

Windows 10 have support for xbox too
I praise myself that I can, directly from the windows shop, among others to buy a specific game or using the Xbox application for Windows 10, I can run streaming from the console directly to the computer. Thanks to this, I do not have to fight with the fiance for the image display device, there are also no major problems with the fact that I go with the console somewhere further - where, for example, connecting it to an external display will be a bit difficult. The only downside of streaming is a bit "annoying" configuration: streaming works best with "cable" and what's more, it's worth turning on the sharing of an active internet connection. Not only that, the user must be logged in to the same account both on the console and on the PC (sometimes it is difficult to get without a picture ...).

For me I use Windows 10 x64, Ubuntu, Mac Os and Windows 7 x64
