Who it is for

People who fix Windows computers: patch remediation teams, desktop support and service desk staff. Each error code has its meaning, likely causes, things to try with the source of each, and where it exists a script that carries the fix out.

Accuracy

Fixes come from published guidance and from tests on real computers. A fix is marked verified here only after someone has recorded that it worked. Always read a fix and test it on a non-production computer first.
