Who writes it
We are a small editorial team. We are independent from the SumatraPDF maintainer, and we ship no fork of the binary. We verify install commands and document features that appear on the official site, licence text, and release notes.
PDF reader is an independent install guide for SumatraPDF on Windows. It links every installer to the official sumatrapdfreader.org download page and the winget package SumatraPDF.SumatraPDF.
How guides are verified
We re-read microsoft/winget-pkgs for SumatraPDF.SumatraPDF, the project download asset list, and the project licence when a new build appears. Commands that were not executed on a physical Windows PC stay marked UNVERIFIED in RESEARCH.md until a real run confirms them.
Why SumatraPDF for this keyword
Criteria: public source, GPL licence text, a winget id with a clear Windows install.exe story, and an official site that documents a free multi-format viewer. If a better-maintained Windows option appears with clearer packaging for the same job, editorial updates would say so.

Corrections
Wrong commands, stale asset names, or accessibility problems go through contact. Factual errors are fixed after verification against upstream sources.
Quiet Windows checklist
Confirm App Installer from Microsoft when the package manager command is missing. Reopen Terminal after App Installer lands, then retry the documented line. Checksums, when published, live next to assets on the official download page. Read COPYING on the project site before you redistribute a modified build under GPL terms.
Keep the first pass short. Open a disposable document, Find once, and confirm the page canvas. Prefer the same update door later so Start Menu shortcuts stay honest after upgrades.
Licence and update habits
Upstream licence text is GPL-3.0 on the official site. Winget locale language matches that free software story for the desktop Windows build. Prefer one install door per PC.
When fleet policy wants a manual install.exe, take it from the same official download page winget already wraps. Stop if a page asks you to disable SmartScreen for an unknown publisher before the official package arrives.
When something fails
If SumatraPDF is missing from Start, confirm the setup finished and avoid downloading a second renamed installer. If Find looks wrong, reopen the document rather than stacking mirrors. Safety and first-run guides deepen those checks without inventing competitor prices.
