• Download the ShareX program and install it using the defaults.
• Once installed right click on the ShareX icon in your taskbar.

• Go to HOTKEY SETTINGS

• Then set your "Capture region" key to be what you like.
• Right click on the ShareX icon in your taskbar once done.
• Go to "AFTER CAPTURE TASKS"  You can choose whether to save to files or not - Unselect anything you do not need
• Hover over AFTER UPLOAD TASKS then make sure you have "Copy URL to clipboard" selected - This means anytime you take an image it auto dumps it to imgur and you have it in your clipboard to CTRL+V ready to go
• TASK SETTINGS You can untick "Play sound after task is completed" and you can untick "Show toast notification" which will hide the preview of the share-x capture if you want to. For me I always keep "Play sound after capture is made" done
