SysManager 1.136.131のダウンロード

[1.136.131] - 2026-11-06
A size just under a megabyte or a gigabyte no longer reads "1024.0 KB" or "1024.0 MB", and a speed just under a megabit no longer reads "1000 Kbps".
Fixed
- Sizes were rounded to one decimal in the unit they fell in, so the top of each unit read as 1024 of it: 1,048,575
bytes read "1024.0 KB" where it is "1.0 MB", and so on up to the terabyte. A size that rounds to 1024 takes the
next unit now. Windows Update's list and the Dashboard's Quick Cleanup had sizes of their own with the same
fault, and use the same figure now. Since 0.48.31, when sizes came to be formatted in one place.
- Network speeds did the same at 1000: 124,950 bytes a second read "1000 Kbps" where it is "1.0 Mbps", in Bandwidth
Monitor and wherever else a speed is shown. Since 1.54.0.
Changed
- The Dashboard's Quick Cleanup says what it freed with one decimal, "Freed 300.0 MB", as Quick Tune-Up does for the
same sweep. It said "Freed 0 MB" for under half a megabyte.

Get-FileHash .\SysManager-v1.136.131.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. 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-v1.136.131.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-v1.136.131.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
