Ladda ner SysManager 1.65.12

[1.65.12] - 2026-08-17
The Bandwidth Monitor's precise mode — the one that needs administrator — was doing its measuring on the
same thread that draws the window, and the amount of work grew the longer you left the tab open. Both are
fixed, so it now behaves like the ordinary mode already did.
Fixed
- Precise bandwidth mode stuttered, and got worse the longer it ran. The 1.61.9 release fixed this
stutter for the ordinary mode and stated that precise mode was never affected. That was wrong: precise
mode did all of its per-second work on the thread that draws the window. Worse, that work kept growing —
it re-sorted every program that had used the network since you opened the tab, so an installer that ran
once in the morning was still being sorted at five o'clock. Programs that have sent nothing for ten
minutes are now dropped from that list, and the measuring happens on a background thread for both modes,
so the cost no longer depends on how long the tab has been open.
Verify the download
Get-FileHash .\SysManager-v1.65.12.exe -Algorithm SHA256
Expected SHA256: DC1E6C02490D1353D2C2CF150D14EF7D0A234BD14737CB6672D81C29E097E584
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-v1.65.12.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-v1.65.12.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
