Lataa SysManager 1.136.21

[1.136.21] - 2026-10-30
DNS presets and Reset to DHCP work again on a network adapter with IPv6 turned off.
Fixed
- On an adapter with IPv6 turned off, a common network tweak, every DNS preset ended in "Failed
to set DNS" and Reset to DHCP in "Failed to reset DNS", and neither changed anything. Before a
change SysManager reads both address families, so Undo can put them back, and Windows keeps no
IPv6 DNS settings to read for such an adapter. SysManager now notes that IPv6 is off and sets
the IPv4 servers alone, after checking that IPv6 is still off, and the confirmation says only
the IPv4 servers are set. Undo resets and restores IPv4 alone, so an IPv6 turned back on in the
meantime keeps its servers. Present since 1.56.4.
Verify the download
Get-FileHash .\SysManager-v1.136.21.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-v1.136.21.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-v1.136.21.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
