How these pages are made

Every step on PC Driver Update comes from a named Microsoft page (support.microsoft.com or learn.microsoft.com). The page title and a link sit above each group of steps, together with the date the page was checked and a credit line that follows that page's license. No step, warning, cause or code name comes from anywhere else.

This site holds 177 codes with steps and 725 more codes with an official meaning only. 46 pages have the full steps (236 steps).

A code, or a group of codes that share the same steps, gets its own page only when the steps from the Microsoft pages give at least 3 distinct steps, or steps from at least 2 Microsoft pages. Other codes are rows in the table of their group, with the official meaning and a one-line summary. Codes with an official meaning but no steps are in the A-Z list and the code search only.

Microsoft Learn pages published under the CC BY 4.0 license are credited with a link to the license, and the steps are shortened and reworded. Pages on support.microsoft.com are not licensed for copying, so the steps from them are short summaries in our own words, with a link to the full steps. When the license of a page is not known, only the page title and the link are given.

Each entry was checked at least twice by an automated process: the first check wrote its steps down from its Microsoft page, and every later check compared them with the text of that page. The dates are in the "Dates and review" section of every page.

First check: the Microsoft page was read and the steps written down (Nov 14, 2026). Second check, Nov 14, 2026: 51 passed after corrections to the steps and 60 passed as written. Third check, Nov 14, 2026: 48 passed after corrections to the steps and 63 passed as written. Fourth check, Nov 14, 2026: 114 passed as written and 63 passed after corrections to the steps.

No entry has been read line by line by a person. The site's editor approved the design and layout, and 139 units were cleared for publishing after the automated checks above. A page that was cleared says "Cleared for publishing after the automated checks on" followed by the date. The pages are built by a program from a data file. Nothing here is tested on a computer by the authors, and no success rate is claimed.

183 steps on this site are flagged because the Microsoft page itself gives a step that changes boot or startup settings, disks, services or policy, or security settings, or that can delete data. A flagged step carries a badge for each kind of change and a precaution line. A step that is not flagged is not a promise that it is safe.

The precaution line under a flagged step comes from a list with 25 entries, one for each kind of change. Each entry holds the advice, the Microsoft page it relates to, and whether Microsoft itself gives that advice (checked Nov 14, 2026 to Nov 15, 2026).

When Microsoft itself gives the advice, the line starts with "Microsoft advises" and names the Microsoft page. Otherwise the line starts with "Our advice" and the Microsoft page is linked only as a how-to. If no precaution is on file for a kind of change, the line says: "Our advice: back up your files before this step." with no link.

The date at the top of a page is the newest date of a check, a read of a Microsoft page or a review of that page's data (the newest on this site is Nov 15, 2026). It changes only when that data changes, never because the site was rebuilt.
