SysManager 1.75.5

[1.75.5] - 2026-08-27

Tune-Up's temp cleanup was reaching into SysManager's own working files. That could make a perfectly
clean run report errors, and in the worst case stop a feature working until you restarted the app.

Fixed

• Cleanups no longer sweep the folder SysManager is running out of. Because the app ships as a
  single file, Windows unpacks part of it into your temp folder while it runs, and both temp cleanups
  — Tune-Up's and Deep Cleanup's "Temporary files" — walked temp without knowing to leave that
  alone. Files the app had open refused to delete and were counted as errors, so a cleanup could report
  failures it caused itself. Files it had unpacked but not opened yet were deleted for real, which
  could break a feature later in the same session — the per-app bandwidth view was the most likely
  one, since it loads its extra components only when you start it. Both cleanups now skip that one
  folder and nothing else, so everything they used to remove is still removed.

Verify the download

Get-FileHash .\SysManager-v1.75.5.exe -Algorithm SHA256

Expected SHA256: 917A6A8239F2D1763DA3595EF975833DD8D8B9B76C421A82CF456CCCC101831D

This build is not code-signed, so Windows will warn on first launch. That is
expected for a small independent app: see what the warning says and what to
click.
Code signing is planned through the SignPath Foundation,
which provides free certificates to open-source projects, with signing performed by
SignPath.io. Until then, the SHA256 above and the build
attestation below are what establish that a download is the genuine build.

Code signing policy

This release is not code-signed. The team roles, release-approval process and
privacy policy required by the SignPath Foundation programme
are documented in advance under Code signing
policy. That
documentation is a prerequisite for applying, not evidence of a certificate. The
attribution line naming SignPath as the signing provider will appear here once a
certificate is actually issued.

This program will not transfer any information to other networked systems unless
specifically requested by the user or the person installing or operating it. Full
privacy policy.

Verify where this binary came from

This exe was built by GitHub Actions from this public source, and the build is
recorded in the Sigstore public transparency log. With the
GitHub CLI:

gh attestation verify .\SysManager-v1.75.5.exe --repo laurentiu021/SystemManager

That proves which commit and workflow produced this exact binary, something the
SHA256 file cannot show, since it is published alongside the exe it describes.
Each release also ships SysManager-v1.75.5.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
