This is only for Windows 10 (and might work for Windows 8/8.1 I guess), some of this doesn't work on Windows 11, such as the taskbar modifications.
There are some things missing from that video, though. I made this for people who generally prefer written guides, but you can also follow this video, which compiles everything into one zip (including WindowBlinds).
Someone who likes that version more might be able to make a specialized tutorial for it. Note that this is mostly meant for the Windows 7 style, though most of this stuff works for Windows Vista desktops too. I've seen a few posts of people putting their Aero-style desktops here before, but there aren't any proper guides on Reddit, so that is what this is.
