how do I split the screen to look at two windows

Left click and hold on the top of the screen you want to split then drag it to the edge of the screen . When you hit the edge of the screen the page will split. Then drag the other page you want to split to the other side of the screen . If your using a browser you need to have 2 windows open you cant split tabs. So open that tab in another window. This is done by right slicking on the tab you want and selecting move to new window.Then you can split the screen. This is in windows 10 . Hope this helps

jenhump depends on what version Windows you are running and what you mean by splitting the screen. In Windows 7 and Windows 8, you no longer have to follow the Windows XP procedure for splitting windows because there is a new feature called Snap. Using Snap, you can just drag windows around the screen and they will “snap” into place. Check here for more.

Yet again rephrasing what both @oldturkey03 and @jimfixer have said, simply open the two programs you want to look at together, click at the top and drag to the side of the screen. When you do this, the other program will want to line up on the other half. Alternatively​, you can hold down the Windows key and use the directional buttons to move to the sides.
