Download SysManager 1.136.31

[1.136.31] - 2026-10-31
Ping's verdict no longer calls your router and DNS clean without pinging them, and counts the
targets you add.
Fixed
- With the CS2 Europe, FACEIT Europe, PUBG Europe or Streaming preset, nothing between your router
and the servers was pinged, so any loss to the servers read "It's the game server, not you" with
"Your connection to DNS and gateway is clean", even when the loss was at your provider. Each of
those presets now pings Cloudflare's DNS server as a reference, and the verdict calls a layer
clean only when it measured something in it. Without a reference it says it cannot tell the
server from your provider.
- A target you added, and google.com in the Global preset, never counted toward the verdict, while
their loss showed under it: a server of your own at 15% loss read "Connection is healthy" above
"15.0% worst loss". They count now, and the verdict names the target in trouble.
- The detail said "loss" whatever had tripped, so a DNS server answering every ping at 65 ms was
reported as losing packets. It now says what tripped: packet loss, jitter or high latency. All
three were there from the tab's first version.

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. Two checks
run on their own when SysManager starts: the version check against the GitHub Releases
API, at most once a day, and the Dashboard's app-updates alert, which asks winget. The
About tab can switch off either. Everything else that uses the network runs only when you
use 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-v1.136.31.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-v1.136.31.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
