To capture a screenshot of a specific area on your screen, you can use the Snipping Tool or the Snip & Sketch app, both of which are built-in to Windows. For the Snipping Tool, open the Start menu, type "Snipping Tool," and select the app from the search results. Once the Snipping Tool is open, click on "New" and select the "Rectangular Snip" or "Freeform Snip" option. Use your mouse to drag and select the desired area on the screen, and the snip will open in a new window where you can save or annotate it. Alternatively, you can use the Snip & Sketch app by pressing the Windows key + Shift + S. This will activate the Snip & Sketch tool, and you can choose "Rectangular Snip" or "Freeform Snip" from the toolbar. Click and drag to select the area you want to capture, and the snip will open in a Snip & Sketch window where you can edit and save it.
