How PCDecoder works
Built from Microsoft's own pages
Every fact comes from Microsoft's documentation and release notes, and every page links its sources.
No invented identifiers
A page that names a KB, build or error code its sources don't contain is never published.
Ordered by what works
Readers' answers to “Did this fix it?” move working fixes up and failing ones down.
