Any chance Cygwin may be running under Hyper-V due to possibly unrequested 
security changes, such as enabling Device Security/Core Isolation/Memory 
Integrity, because of enabling logging/reporting back to MS, or checking 
signature on each execution of each executable, or other "security" features (by 
default bypassed by buggy/unsafe MS products, which are the ones that need it)?
