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)? -- Take care.
