On Windows, there are several ways to take a screenshot:

Using the Print Screen key on your keyboard

• Press the Print Screen button on your keyboard. This will capture an image of your entire screen and copy it to the clipboard.

NOTE: The Print Screen button may be labeled as PrtScn, PrntScrn, Print Scr, or similar. On most keyboards, the button is usually found between the F12 and Scroll Lock keys. On laptop keyboards, you may have to press the Fn or Function key to access Print Screen. You will not receive any confirmation that the screenshot has been taken.

• Paste the screenshot into a program in order to see it. The most common way is to paste it into a Paint file so you can transfer it later on.

• Click on the Windows icon in the lower left corner of the screen and type Paint.

• Click on Paint to open the app.

• Once the new blank canvas is open, press Ctrl+V keys simultaneously to paste the image onto the canvas. You can also open the Edit menu and select Paste, or right-click on the canvas and select paste.

• Click File, and then Save to set the name, file type, and location of the image.

Taking a screenshot of the active window

• Hold the Alt key, then press Print Screen. This way, you will only take a screenshot of the active window.

• Click on the Windows icon in the lower left corner of the screen and type Paint.

• Click on Paint to open the app.

• Once the new blank canvas is open, press Ctrl+V keys simultaneously to paste the image onto the canvas. You can also open the Edit menu and select Paste, or right-click on the canvas and select Paste.

• Click File, and then Save to set the name, file type, and location of the image.

Using Snipping Tool

• Click on the Windows icon in the lower left corner of the screen and type Snipping Tool.

• Click on Snipping Tool to open the app.

• Click on New, then drag the cursor along your screen to select the area you want to capture an image of.

• After that, you can save the image by clicking on File and selecting Save As.

• Type the name of the screenshot, choose the file type, then click on Save.

Using the Windows key + Print Screen combination

• Hold down the Windows key on your keyboard and then press the Print Screen key.

• Hold the Windows key and press E on your keyboard to open Explorer. Click on the Pictures library, located in the left-hand side of the screen.
