WHY AREN'T YOU USING Q4OS
It has Q in the name. Debian Linux with the Trinity Desktop Environment (KDE 3f fork). It's nice and secure, much better than Winblows.
Yes via wine.
It's just a theme, you can theme Linux to look however you want. Personally, I like the default theme that comes with Q4OS since I like the Windows look. Ubuntu is based on Debian and Q4OS is also based on Debian, though it's a lot closer to base Debian than Ubuntu is.
There are alternatives to 99% of Windows software. You sound like a brainlet though, keep using CIA/Clown-approved Windoze.
