Download SysManager 1.75.1

[1.75.1] - 2026-08-26
"Restore original cores" on the CPU Core Affinity tab could report success while putting nothing back.
If you pinned a process and then refreshed the list, Restore quietly re-applied the cores you had just
pinned instead of the ones the process started with — and still said it had restored them.
Fixed
- CPU Core Affinity: Restore now really returns a process to the cores it started on. The tab
remembered "original cores" in a single slot that was re-read every time a process was selected, so
refreshing the list after pinning overwrote the remembered value with the pinned one. Restore then
wrote that same mask back — a no-op reported as a success. Each process's starting affinity is now
captured once, the first time the tab sees it, and kept for the rest of the session. Two related
edges are covered as well: the remembered value survives a refresh (so the button no longer
disappears), and Restore is not offered at all for a process whose affinity could not be read,
rather than being offered for a restore that would do nothing.
Verify the download
Get-FileHash .\SysManager-v1.75.1.exe -Algorithm SHA256

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-v1.75.1.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-v1.75.1.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
