ดาวน์โหลด SysManager 1.87.1

[1.87.1] - 2026-09-10
Opening the Startup Manager no longer reaches out to the internet. The Signature column checks
each program's certificate against your own machine, and it was written to do that without asking any
server anything — but Windows has a second, separate switch for that, and it was left at its default.
So on a PC that had not seen a particular publisher's certificate before, checking the column could
quietly fetch part of it, and on a PC with no connection at all it could sit and wait for that fetch to
time out. It now asks nothing and answers immediately.
Fixed
- The signature check on the Startup Manager makes no network request. Turning off the revocation
lookup, which the tab already did, does not turn off certificate downloads — that is a separate
setting, and it defaults to on. Both are now decided together, so a check that was chosen to stay
local actually stays local.
- On a machine with no network, that column no longer waits out a download timeout per unfamiliar
publisher before it can draw.
- The two places that verify a single file and should use the network — the in-app updater checking
a downloaded build, and the check on the third-party speed-test tool before it runs — keep it. There,
fetching a missing intermediate certificate is what lets a genuine signature verify, and the wait is
part of an action you asked for.
Verify the download
Get-FileHash .\SysManager-v1.87.1.exe -Algorithm SHA256
Expected SHA256: EADE5799A96CC81D01D4C315B7852AC6BF6C47C333E8043A43A098E60D3EEF96
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-v1.87.1.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-v1.87.1.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
