The only advice i can give is to treat tskill failures gracefully. W32
is known to put processes into a state in which they still exist, but
cannot be interacted with, probably due to the fact that OS is
dismantling them at the moment. Killing such process at that time will
fail with "Access denied", no matter who you are or what permissions
you have.
If that happens, i'd advise to wait for a second or two (the best way
is to wait on process termination, but that requires Win32API; you can
instead just wait for short amounts of time in a loop, then check
whether the process is dead; or just wait for the full amount of time,
if performance is not a goal), then check if the process is still
alive and try again if it still is.
