To take a screenshot in Windows 10, there are several common methods:

1. Press the "Print Screen" (PrtScn) key to capture the entire screen. This copies the screenshot to the clipboard, and you can paste it into an image editor (e.g., Paint) using Ctrl + V and save it.
2. Press "Alt + Print Screen" to capture only the active window. This also copies to the clipboard for pasting and saving.
3. Press "Windows key + Print Screen" to capture the entire screen and automatically save it as a PNG file in the "Screenshots" folder inside the "Pictures" folder.
4. Use the shortcut "Windows key + Shift + S" to open the Snip & Sketch tool, which allows selection of rectangular, freeform, window, or full-screen snips. The capture is copied to the clipboard and shows a notification to edit and save.
5. Use the Snipping Tool app for customizable screenshots including freeform and window snips, with editing and saving options.

These methods provide flexibility depending on whether you want quick copying, direct saving, or more control over the capture area.
