I've been using the Sysinternals tools for close to two decades and got used to certain keyboard shortcuts. In the later (themed) versions of your tools a lot of these no longer work.
As examples for Autoruns:
Keyboard focus is not on the list at start, in fact focus seems to be "nowhere" in the UI and I have to click inside to focus the list.
Using Space to disable an item is not working as it used to
Opening the context menu using the menu key (next to RWin) is not working. Neither is the old Shift+F10.
Ctrl+M to search online is not working
Alt+Enter to see properties is not working
Moving around the application (i.e. from list to tabs to filter) using Tab is not working
Knowing how important good accessibility is to Microsoft, this is quite disappointing, good keyboard access is a huge time-saver and can help avoid RSI.
Please fix keyboard accessibility in your tools instead of adding fluff like dark themes.
