A one-stop, do-everything calculator

Reor is a free calculator with a surprising amount of features and functionality.

The program opens with the most basic of interfaces: numbers, four operators, "=", "C" - even the most math-challenged will feel at home immediately.

Tap the menu, though, and a vast number of other modes appears on a full-screen display. In a click you can view Scientific, statistical or financial functions, a graphical plotter, lists of physical and mathematical constants, a mortgage payment calculator, unit converter and more.

Unlike many other calculators, the core interface doesn't rework itself to suit the new mode. Switching to Scientific mode, say, just gets you a separate dialog with buttons like "cos", "sin" and "tan" which you select as required.

There are also some unexpected extras. A "wordify" function presents your currently-displayed value as words, for example, while a full History view gives you access to all the calculations you've performed so far.


Reor's interface is occasionally annoying. Does the main menu really have to display full-screen, on top of every other application? But it's a capable calculator, worth a look if you've outgrown Windows' own offering.

Windows 10 May 2019 Update ISO (build 1903)

Free Full Commercial Software

This is the latest version of Windows May 2019 Update. it's a media creation tool that can be used to upgrade an existing installation of Windows or create installation media for another PC. Just make your choice after launching the tool and it'll do the rest.

What was new in Windows 10, when it was released? The OS brought back the Start Menu, though with a twist: live tiles keep you up-to-date with the latest news while also providing an easy way to launch apps. (Don't worry if you prefer the Start Screen, it's still there and you can boot into it if you prefer.)

Apps now work much more like regular desktop programs. They have minimise, maximise, restore and close buttons, and can be resized (to a degree) and organised however you like.

If you've still lost track of a program in the mass of open windows, a new Task Spaces feature can help. Click its taskbar button and you'll see thumbnails for everything running now, a little like OS X's Mission Control - just click something to switch to it.

Better still, Task Spaces also supports virtual desktops. Add extra desktops as required and it'll display thumbnails of each one, making it easy to identify whatever you're after and switch to it.

There's also smarter snapping, new customisation options, and even a bunch of experimental additions to the command prompt.

May 2019 Update brings a whole host of new features for Windows 10. See the Microsoft Blog for more information.

The Windows 10 ISO will give you build 1903 which is the May 2019 Update.
