If you have a lot of apps open, Alt-Tab no longer shows them all, you have to repeatedly keep bashing Tab to get the window to scroll down to the hidden ones - there's no scroll bar and mousewheel doesn't work. For this reason, I've completely stopped using Alt-tab on Windows 10.

Win+Tab is the 'replacement' but is slower and riddled with bugs - one annoying one is that some times it doesn't show the preview of half the apps. Also, the order of the windows is always changing, so you waste time scanning for the app you just used.

You can also type Win+<num> where <num> is 1-9 and that number icon activates from the taskbar. Which is great if you have 10 sticky icons down there, but if like me you don't 'stick' icons to the taskbar, it not as fast (muscle memory etc) or as useful as it could be.

I totally agree with the first part of his video (the main Windows 10 rant). Each iteration of Windows makes it slower for the power user. When the Year of the Linux Desktop is finally upon us, I guess I'll eventually switch. ;)
