SysManager 1.52.94

What's new for you

A performance fix: the Dashboard no longer re-scans your disks over WMI every 2 seconds just to label the temperature sensors. Disk names are read once and reused, so the live vitals poll is lighter on CPU and disk — especially noticeable on machines with several drives.

[1.52.94] - 2026-07-11

Fixed

• The Dashboard's 2-second temperature poll re-ran a Win32_DiskDrive WMI query and a per-disk SMART association walk on every tick, purely to relabel storage sensors with (unchanging) disk names. RefreshTemperaturesAsync calls TemperatureService.ReadAllAsync() with includeStorage defaulting to true; on an elevated session that ran GetDiskNamesFromWmi() (a Win32_DiskDrive query) and EnrichStorageNamesAsync → DiskHealthService.CollectAsync() (an MSFT_PhysicalDisk enumeration plus a per-disk MSFT_StorageReliabilityCounter walk — by the code's own comments "by far the heaviest part of a read") every 2 seconds while the Dashboard (the app's default tab) was open. Disk friendly-names are static hardware identity, so both resolutions are now memoized once (mirroring the existing _nvApiInitTried "resolve static hardware once" pattern), with a SemaphoreSlim gate making the first resolution race-safe across the 2s poll, the user's Refresh, and the 10s resource sampler. After the first read the hot poll only calls LibreHardwareMonitor's Update() for live temperatures.
