Screen Clip

Ever since the introduction of "Screen Clip", this has been built into Windows.

1. Use win+shift+s
2. Create a screenshot.

And you're done. This will have been copied into your clipboard and will have been written to file in a special dir inside your user accounts's local appdata folder. To find out where:

1. open cmd or powershell
2. cd C:\Users\YourUserName\AppData\Local
3. dir ScreenClip /s

That'll find you the location of the screenshots dir (the current location as of April 2021 is C:\Users\YourUserName\AppData\Local\Packages\MicrosoftWindows.Client.CBS_cw5n1h2txyewy\TempState\ScreenClip, but it's changed a few times over the years). You can now do whatever you like with it...
create a shortcut on your desktop named "screenshots" for that folder open it in windows explorer and favorite it add a bookmark for it in your preferred file manager etc. etc.
