Step 1: Capture the image. Ensuring the area you want to capture is displayed on your screen, press the Print Screen button typically located in the upper right-hand corner of your keyboard to capture a screenshot of your entire display. Alternatively, press Alt + Print Screen to capture a screenshot of the single, active window. Keep in mind there will be no noise or any other indication the screenshot was taken, but the resulting image will be saved as a PNG file to your clipboard.
Step 2: Open Paint. Click the Start Menu, navigate to the Accessories folder, and click Paint from the list of native Microsoft software. The icon depicts a painting palette with a brush on the right-hand side, but it will vary slightly from OS to OS. Alternatively, search and open the program from the Windows search bar.
Step 3: Paste the screenshot. Once open, click the Paste button in the upper left-hand corner of the program, choose Edit then Paste, or press Ctrl + V on the keyboard to paste your screenshot. The exact navigation will vary slightly from version to version, but the keyboard shortcut will remain the same.
Step 4: Save the screenshot. Perform any edits you want, such as cropping the image to a specified area, and click the main File option in the top-left corner. Afterward, select Save as, title the new file, choose a save location, and select your desired file format from the drop-down menu. For most purposes, JPG will do fine, but a variety of other formats are available to choose from such as PNG, BMP, GIF, and others. Click the gray Save button in the bottom right-hand corner when finished.
