On my samsung laptop [ ksapi64.sys ] running windows 11, this file is showing up as incompatible driver, keeping memory integrity from being turned on. I'll have to delete if no replacement can be found, any further info would be appreciated, thanks. P.S. apparently M.S. doesn't have answer, waiting to hear back from them.
