KiXtart 4.66 (and I assume all previous versions) cannot get the "real" file versions of Windows 10 exe/dll.

See Targeting your application for Windows

An app manifest manifest would correct this issue - note that signed w/kix32.exe would also be greatly appreciated ;\)

Example:
 Code:
? getfileversion(expandenvironmentvars("%SystemRoot%") + "\system32\wuapi.dll", "BinFileVersion")


KiXtart: 6.2.10586.0
Expected result: 10.0.10586.0
