Connecting to a remote Windows desktop can be done using the free Microsoft Remote Desktop app
You'll see the remote PC's desktop and your fingertip moves the mouse cursor. To switch to touch controls, as if using a touchscreen PC, tap the IP address toolbar at the top of the screen, and select the option at the bottom right on the sidebars that appear. To bring up a keyboard for typing, tap the keyboard icon in the toolbar at the top of the screen.
To disconnect, tap the toolbar and then tap the X at the left of the thumbnail listing at the left of the screen.
