What improvements have been made to Win10 Preview 9926?

Alarm Clock

After updating Win10 Preview 9926, we feel that Microsoft should change the name of the application to "Alarm clock". The app now includes four tabs: Alarm Clock, World Clock, Timer and Stopwatch. The button is also replaced with a rounded shape.

The background of the world clock can tell you where the sun is shining and what is coming at night. There is also a more convenient feature, which is that it allows you to set a time, a specific place, and find out its date at other times. You can also attach it to the start screen/menu for use.

Timers and seconds can help you better control your time, such as making it easy for users to test 500-meter sprints. These two functions can also be fixed on the start screen/menu.
Calculator

Win10 Preview Edition 9926 calculator uses a new UI, which is very different from the calculator that was previously installed on Win7. In fact, Microsoft has adopted this UI in Win8, but it is now complete. The new calculator is in a smaller window, but the buttons get bigger and easier to click. You can still switch between the standard calculator and the scientific calculator.

In addition to calculations, the calculator app also has a built-in converter that allows users to convert units. It consists of seven units including length unit, temperature unit, speed unit and pressure unit. You can easily know how many meters a mile is equal to the converter.
Map
The map interface of the new Win10 preview version has also been simplified, and the design is more concise. You can change the perspective and direction of the map to find “my location”, control the zoom. On the right is a sidebar that gives you access to search, favorites and settings.

Collections are synced to multiple devices using the same Microsoft account. You can also easily access nearby hotels, restaurants and other shopping venues.

The map also supports the use of offline maps. Users can download the map to the device and use it in a network-free environment.
In addition to the three applications of alarm clock, calculator, and map, Microsoft has optimized many other applications. You can explore these improvements yourself in your usual use
