I did a fresh cygwin-64 (setup-x86_64 version 2.870) install under build 10061 of Windows 10 Technical Preview.
The group permissions in the root look wrong. $ ls -lA / total 321 drwx---r-x+ 1 Brian Brian 0 Apr 29 10:31 bin dr-xr-xr-x 1 Brian Brian 0 Apr 29 10:31 cygdrive -rwxr-xr-x 1 Brian Administrators 59 Apr 29 10:31 Cygwin.bat -rw-r--r-- 1 Brian Administrators 157097 Apr 29 10:31 Cygwin.ico -rw-r--r-- 1 Brian Administrators 53342 Apr 29 10:31 Cygwin-Terminal.ico drwx---r-x+ 1 Brian Brian 0 Apr 29 10:31 dev drwx---r-x+ 1 Brian Brian 0 Apr 29 10:31 etc drwx---rwt+ 1 Brian Brian 0 Apr 29 10:31 home drwx---r-x+ 1 Brian Brian 0 Apr 29 10:31 lib dr-xr-xr-x 9 Brian Brian 0 Apr 29 10:31 proc drwx---r-x+ 1 Brian Brian 0 Apr 29 10:31 sbin drwx---rwt+ 1 Brian Brian 0 Apr 29 10:31 tmp drwx---r-x+ 1 Brian Brian 0 Apr 29 10:30 usr drwx---r-x+ 1 Brian Brian 0 Apr 29 10:30 var I'm logged on with a Microsoft account and ran the installer as an Administrator.

Is there a way to fix the permissions or a workaround for installation?
