The situation when you have to use several programs at the same time is a common thing for a computer user. Application programs run in windowed mode, and switching from one window to another is as easy as shelling pears. But if one of these programs is a computer game, everything turns out to be a little more complicated due to the fact that applications of this type are launched in full screen mode by default.
Instructions
Step 1
Try the easiest way to switch from full screen to windowed mode - while the game is running, press alt="Image" + Enter. If it doesn't work, check to see if the manufacturer has used any other fairly common counterparts of this command - the F11 key and the Ctrl + F combination for Windows or Command + M for MacOS.
Step 2
Another way to do without manual editing of game properties is to use the switch to windowed mode from the program settings. This option is also not available in all games, but it's worth checking - in the menu of the running application, go to the Settings section and look for the "Windowed mode" setting or something similar to it. If such a setting exists, check the box and save the changes.
Step 3
If you can't get by with the controls of the game itself, try adding the appropriate modifier to the program launch line. To do this, right-click on its shortcut on the desktop and select the "Properties" line in the context menu. If you use the item in the OS main menu to start, then do the same with the line in the menu. As a result, a window with a highlighted line in the "Object" field will appear on the screen.
Step 4
Go to the end of this line (End key) and add the -window modifier after a space. Then click the OK button and run the application. This method allows you to launch Counter Strike, Warcraft, Mass Effect, etc. in a window. If it does not work in your game, try changing the modifier - for example, windowed mode in Sims 2 is enabled by adding -w, and besides this option, -win is possible.
Step 5
This option can also be enabled through the settings file, if, of course, it is provided by the manufacturer. To find out, go to the game folder and look in the files for the text Fullscreen or Windowed. In Windows 7, this can be done using the search box in the upper right corner of the "Explorer" window, if you click the "File Contents" icon after entering the text. The Fullscreen setting in the settings file must be disabled, i.e. assign it a value of 0, and Windowed - enable, i.e. assign 1.
