QuoteWith Windows 10 VerifyVersionInfo is now subject to the same
manifest-based behavior as GetVersion(Ex): by default
IsWindows8OrGreater and earlier will return 'true' as expected on
Windows 10, but both IsWindows8Point1OrGreater and
IsWindows10OrGreater will return 'false' without the appropriate GUIDs
present in the <compatibility> section.
So lazarus manifest settings must be updated or you must include your
own manifest with these settings if youre using these stuff. Direct3D
full-screen applications, High-DPI support including per-monitor
scaling or GetVersion(Ex).

GetVersionEx is used in Sysutils unit for win32: CheckWin32Version
depend on this. If you want to get the righ OS number you must ensure
to update your manifest.

Now I use always my own manifest file, those interested in using this
and doing through IDE must report it in bug tracker as new feature
request. In the past I recommended the dpi settings and elevation
settings.
