Although I’m showing WDC for this guide, this is meant to show you how to create a sort of toolbox for your PC.
I’m using Start11 for this guide. I use it on all my Windows machines. It’s a paid program. No, I don’t get a cut.
This is long. If you get confused, please see the pictures below.
I keep a folder of portable tools that I use on every system. From there I create a menu I can access by either my start menu (via Start11) or the system tray.
