[New-bugs-announce] [issue39413] Implement os.unsetenv() on Windows

[STINNER Victor]

New submission from STINNER Victor <vstinner at python.org>:

os.unsetenv() is documented to be available on Windows, but it's not.

In Python 3.8, "del os.environ[key]" is implemented as:

   os.putenv(key.upper(), "")

Attached PR implements it using SetEnvironmentVariableW(name, NULL).
