Thanks for the info.

Depends.  As for the actual cause why userenv.dll refuses to load, no.
It's just a simple LoadLibrary call, nothing fancy.  I just tried the
same scenario on my local 8.1 test machine and logging in with an
unprivileged account worked fine.

I tried to come up with a workaround for the problem, though.  I just
uploaded a new developer snapshot to https://cygwin.com/snapshots/

Just fetch the latest 32 bit cygwin1.dll,
http://cygwin.com/snapshots/x86/cygwin1-20150311.dll.xz

Unxz it, chmod +x it.  Stop all Cygwin processes.  In Windows Explorer,
open the C:\cygwin\bin directory.  Rename the original cygwin1.dll to
cygwin1.dll.ORIG.  Move the new cygwin1-20150311.dll into place and
rename it to cygwin1.dll.  Retry your scenario.  And please report back.


Thanks,
Corinna
