it always use %windir%/temp for firewall , scanings. Problem is windows installer not very like when windows temp folder changet + put it as example to ram drive no good solution for windows update service.
So best solution will be if node can create at future own ram drive how user choice option for temp files when scaning
( i have 128 gb ram so fo users like me that will be good option for utilize it for scaning speedup and lower load static drives )
or at least it will use some folder name for temp files like windows/temp/node/node6612, node7712 etc. ( then will usable symbol links ) - not it work like windows/temp/node files
i was try pay with service ekrn parametrs at regestry add there "set temp folders" , but seems that not work.
