I'm not familiar enough with the Windows performance counters API to know if this is possible, but it'd be useful to have an advanced setting which could set an allowlist and/or blocklist for performance counters.

The reason for this request is when TrayStatus loads it results in several warning and error events being logged to the Application event log. For at least some (all?) of these events it appears that there's no issue with the performance counters themselves, but due to TrayStatus trying to open counters which are privileged (e.g. Lsa, Server). As such, they always fail and an event is logged.

All good, thanks for looking into it Owen. I had a feeling that might be the case as I couldn't see any facility to exclude or filter performance counters in the Windows API docs. Might be worth documenting somewhere if you have a suitable place, for other people who see this issue and wonder what's going on, but it may be so edge-case to not even be worth that.

Thanks again!
