Last week, we’ve added application compatibility manifests to LibreOffice libraries and executables. This is intended to allow the program to run in current OS context, instead of switching to a previous (namely, Windows Vista in case of absent manifest section) OS compatibility context. The effects of this are listed in a MS KB (this is alternative link just in case).
Currently we declare compatibility with Windows 7 through Windows 10. This change is integrated into current master towards LibreOffice 6.0.
