Windows is designed for multitasking. Yes, that means you can open and switch among different apps and windows. But it also means you can arrange those windows so they all appear on the screen together.
Before we check out Snap Assist in Windows 10, let's look at a couple of other ways to organize your open windows.
1. Show windows stacked
First launch a few different apps. Don't worry about how they're arranged on the screen. One way to organize open windows is to stack them, which puts them into columns with one window placed vertically on top of another. The layout will vary based on how many windows are open and the size of your monitor. Right-click on the taskbar and select the entry for Show windows stacked. All windows are arranged one on top of the other.
2. Show windows side by side
Next, you can view your windows side-by-side. This is similar to stacking them, but here the windows are organized more as rows. The layout will vary based on how many apps are open and the size of your monitor, so you may see little or no difference between stacked view and side by side view. Right-click on the Taskbar and select Show windows side by side. Your open windows display in rows one next to the other.
3. Arrange windows through Snap Assist
Potentially more effective is Snap Assist. With Snap Assist, you can precisely arrange your open windows, so they each take up a specific area on the screen. For example, Snap Assist is a helpful way to display two windows side by side, especially if your screen is crowded with multiple windows.
First, make sure Snap Assist is enabled. Go to Settings > System > Multitasking. Confirm that the switch for Snap windows is turned on. Leave all the options under the setting checked.
Choose one of two windows that you want to arrange on the screen. To snap that one to the right, hold it down by the title bar, and move it to the right until you see a faint vertical bar down the middle of the screen. Then release your mouse. Alternatively, select the window and then press Win+Right Arrow Key to snap it to the right. You can also snap it to the left by dragging it there or selecting it and pressing Win+Left Arrow Key.
The other side of the screen will display thumbnails for all your other open windows. Just click the window for the app that you want to view side by side with the first window.
You can snap three and four or even more windows, depending on the size of your monitor and your screen resolution. To snap three windows, pick the first one you want to arrange. Drag it to the right or press Win+Right Arrow Key. Select the second app, and it appears on the left side.
Return to the first app and press Win+Up Arrow Key to snap it to the upper right. Go back to the second app and press Win+Down Arrow Key to snap it to the lower left, and then Win+Right Arrow Key to snap it to the lower right. From the thumbnails on the left, click the app you want to see on the left side.
To now snap a fourth window, select the window on the left and press Win+Up Arrow Key. Then select the thumbnail for the fourth window, and it snaps into place on the bottom left.
Multitasking in Windows 11
Windows 11 is better at multitasking and splitting your screen thanks to visual and practical improvements to Snap Assist. To confirm that Snap Assist is enabled, go to Settings > System > Multitasking. Make sure the switch is on for Snap windows. Leave all the options below it checked.
Open four different apps in Windows 11. Pick any window and hover your mouse pointer over its Maximize icon. As you hover over the icon, you'll see previews for four or more different layouts. The number of layouts will vary depending on your screen resolution and the size of your monitor. On my 13-inch laptop, for example, I get four layouts.
Let's say you want to snap two of the open windows so they appear side by side. The first layout will position them side by side with each window taking up the same width. Hover your mouse over that layout and then click one of the two zones in that layout. Clicking the zone on the left will position your current window on the left side of the screen, while clicking the zone on the right will position it on the right side of the screen.
You'll now see large thumbnails for the other three windows on the other side of the screen. Click the window that you want to see side by side with the first window.
Next, hover your mouse pointer on top of the Maximize button for either open window. This time, choose the second layout and select the larger zone. This one provides more width to your current window and places it on the left side of the screen. Then click the thumbnail for the app that you want to view on the other side of the screen.
Next, let's try snapping three windows. Again, hover your mouse pointer over the Maximize button for one of the two displayed windows. Hover over the third layout and select one of the three zones depending on where you want to place the current window.
The remaining window appears in the fourth spot. Click that window to display it in that spot.
Finally, another way to multitask and split your screen in both Windows 10 and 11 is to use the PowerToys tool called Fancy Zones. With this tool, you can create and apply specific types of layouts to view all your open apps and windows.
