Installed Win 10 today and gave BBZero a whirl.
It loads just fine and I could set it up as the user shell. So far, so good. I have run into two minor issues though.
1. I get no wallpaper. This is most likely because Win 10 links the wallpaper stuff closely to Explorer. Is there any workaround or remedy? A BBlean plugin maybe (with a slideshow function)?
2. The titlebar in bbLeanSkinned windows is awfully transparent. I can't see the window buttons without a dark background and so far, I couldn't find any line in bbleanskin.rc to turn this of or tone this down.
Regardless, I like what you did with BBLean. Keep going and never stop!

Regarding item #2.
I think I found the line (bbleanskin.titlebar.iconHue) in bbleanskin.rc.
However, I noticed a problem with bbLeanSkin.
Whenever I change something in bbleanskin.rc (with the built-in editor or by editing the file with Notepad) and doe "Blackbox -> Restart", BBZero will become unresponsive. I have to kill the process, log out via Task Mananger and then log back in to see the change.
This does not happen if the log window is enabled and open.
Sorry if this is a known bug. I'm not quite "there" today and still pretty giddy from the W10 upgrade.
(P.S: I'm in favor of a binary packacke for future versions. I don't really like installers and it'd make upgrading easier.)
- edit2:
Closed bbLeanSkin's log window and then unchecked the "skin windows" option in BBZero's menu. BBZero hung again and had to be killed.
I'm running a 64bit Windows 10 with a 64bit BBZero build, by the way.
- edit3:
Found out that the freezing is related to Win 10's Defender. That thing is so paranoid that it slows the entire PC down to a crawl and prevents BBZero from doing its job.
Disabled Defender and installed Antivir. Rebooted and now I can adjust bbLeanSkin's settings and restart BBZero at will without any hangs whatsoever.
This still leaves the wallpaper issue...
