See DPI Awareness in Task Manager in Windows 10

If you are following Windows 10 development, you may already know that Windows 10 Build 18262 adds a new column to the Task Manager app, which allows viewing DPI awareness for apps. The column can be enabled on the Details tab.

Windows 8 and Windows 10 have a new Task Manager app. It looks completely different compared to Windows 7's Task Manager and has different features. It can analyze the performance of various hardware components and also shows you all the processes running in your user session, grouped by app or process type.

Windows 10's Task Manager has some nice features, like a performance graph and startup impact calculation. It is able to control which apps launch during startup. There is a special tab "Startup" which is designed to manage startup apps.

Tip: You can save your time by creating a special shortcut to open the Task Manager directly on the Startup tab.

Also, it is possible to make Task Manager show the command line of apps on the Processes, Details and Startup tabs. When enabled, it will allow you to quickly see which folder an app is launched from, and what its command line arguments are. For reference, see the article

In addition to these great features, Task Manager is now able to show DPI awareness for processes. This feature is available in Windows 10 code name 19H1, starting with build 18262.

Desktop applications that are system DPI aware typically detect the DPI of the primary connected monitor on startup. During initialization, they layout their UI appropriately (sizing controls, choosing font sizes, loading assets, etc.) for the dynamic display scale factor. DPI-aware applications are not DPI scaled by Windows (bitmap stretched) on the display.

To see DPI Awareness in Task Manager in Windows 10, do the following.

1. Open Task Manager. If it looks as follows, switch it to the full view using the "More details" link in the bottom right corner.
2. Switch to the Details tab.
3. Right-click on any column in the list of the app entries. Now, click on the Select columns item in the context menu.
4. In the next dialog, turn on the column DPI awareness to enable it. 

You are done.
