[PATCH 0/2] MR2090: taskkill, taskmgr: Use exit code 1 when terminating processes.

[Brendan Shanks (＠bshanks)]

It isn't officially documented but `taskmgr` and `taskkill` on Windows both use exit code 1 when terminating processes, and Chromium treats those exit codes differently (see [kill.h](https://source.chromium.org/chromium/chromium/src/+/main:base/process/kill.h...)).
