Windows Error Code Reference
Windows Update errors, blue screen stop codes, Device Manager codes and application errors. Each record explains what the code means and lists fixes from safest to most invasive.
Each record opens with what the code means, then lists likely causes and fixes ordered from the safest and most reversible to the most involved. Where a fix can lose data, the record says so first. Commands are given for an elevated prompt; back up important data before running repairs on a system that is already unstable.
For codes not covered here, Microsoft's own references are the authority: the System Error Codes, Windows Update error reference and Bug Check Code Reference.
