Records hardware check 109 in docs/hardware-checks.md: the released 0.4.8, installed in Program Files, updates itself to the released 0.4.9. This is the "After the release" item of #69.

Result: pass, with one thing not seen

Checked on 2026-11-12, 23:27-23:33, on the RTX 5070 with driver 621.14.

• Install 0.4.8. The v0.4.8 release zip (SHA-256 checked) was installed in Program Files with its own gao --boot on. The tray started from there and applied the tune; the strike cleared after 2 minutes.
• Update offered. The 0.4.8 window showed Update available. Its tooltip named 0.4.9 as available; the owner saw this on screen.
• Update installed. After the click (23:30:36), Program Files held 0.4.9 within 2 s and the app had started again (--resume).
  • gao.exe and GpuAutoOptimizer.exe match the v0.4.9 release zip byte for byte.
  • Only the two programs were replaced; the exe of the old window was left as .old-.
• Kept.
  • The saved tune: all: 2932 MHz at 960 mV, +270/+1850, saved 2026-10-17 23:31. The date is the same in gao --status and in gao.json.
  • The fan curve, apply at logon, and the logon task BootApply.
  • gao.json is byte for byte the copy taken before 0.4.8 was installed.
  • strikes: 0 of 3. The Application log has no errors from the app.
• Not seen: a real Windows sign-in or restart after the update. The logon task is unchanged, but the copy that starts at logon was not watched starting from it.
