MAUS-0.8.1 alpha

MAUS (Maintenance · Audit · Updates · Security) is a free, open-source (GPL-3.0) Windows 11 utility: a read-only audit first, then fixes chosen by the user, each one explained and reversible. MAUS is designed and coded with Claude, an AI by Anthropic, under the direction of its author.

This is an alpha version in active development: some features may be incomplete and bugs may occur.

Download: MAUS-0.8.1-installation.exe (installs to Program Files, .NET included, uninstall from Settings > Apps).

Build provenance: this installer was built by GitHub Actions from this repository; anyone can check it with gh attestation verify MAUS-0.8.1-installation.exe -R TERMINATORmdel101/MAUS.

Not signed: this installer has no code signature yet, so Windows SmartScreen may show a warning ("More info", then "Run anyway"). Our application for free signing by the SignPath Foundation was declined for now (the project is still too new); we will apply again later.

What's new since 0.8.0

• No administrator prompt when MAUS opens. MAUS now starts without administrator rights and without launching its engine. A MAUS message offers to enable all features ("Yes, I want all the features" shows the Windows permission prompt; "No, continue without" keeps MAUS read-only; the offer can be turned off, and back on in Settings).
• Permission asked only when needed. The administrator engine (same closed list of operations, same private channel restricted to the user and to the window that started it) starts at the first action that needs it: audit, applying or undoing a fix, fix history, Windows repair, driver actions, advanced sensors (new "Enable advanced sensors" button), memory details, driver latency, frame counter, weekly audit. Declining cancels only that action; MAUS stays usable without rights.
• Administrator rights close by themselves after 15 minutes without a request (never during a request, a benchmark or a stability test), and when the window closes. The next action asks again.
• Benchmark: with the PawnIO driver installed, starting the benchmark asks for permission so that the processor temperature safety stop works; declining still runs it, with the graphics card safety stop only.
• Display choices (language, theme, frame counter, search engine) are now stored in the user's own folder; choices that drive the audit and fixes stay in the administrators-only folder and only go through the engine.
• Memory tab (Intel Core 6th to 10th gen): memory clock checked against the speed reported by Windows (it was shown doubled on a Coffee Lake PC with DDR4-4000), durations in nanoseconds corrected, CAS latency in nanoseconds, tWR and tRTP shown and marked as derived, tRCD and tRP on one line (a single value in this controller), memory sheet comparison in MT/s.
• Microsoft Store package: the Windows component store check now works inside the package (the in-process DISM API failed there; dism.exe /CheckHealth, read-only, is used instead).
