The build number could be obtained from the value of the registry key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\CurrentBuildNumber

but it seems not to be worth the trouble. In 51336af I instead changed the test of reserved names on Windows to ignore any `IOException` thrown by `File.createTempFile`. The change was verified on the aforementioned Windows variants and on Linux and macOS.
