Use Segment Heaps for memory (de)allocation if available via manifest opt-in. This applies to Win10 version 2004 and newer (such as Win11) otherwise falls back to the default NT Heaps. https://learn.microsoft.com/en-us/windows/win32/sbscs/application-manifests#heaptype
Testing shows that this reduces memory usage a little bit. attributes related to memory fragmentation have not been tested however Segment heaps are supposedly better in this regard as well.
!heapin WinDbg can be used to confirm that the memory heaps of the process(es) are indeed being allocated with the newer heap type.
