Facts first.
Sarcasm second.

Purpose

The archive makes Windows update failures easier to find and compare. It records the originating update, what broke, which systems or features were affected, the severity of the impact, and whether a resolution has been documented.

It is a historical reference, not a real-time service-status page or a substitute for Microsoft support, release health documentation, tested backups, or advice from your system administrator.

What qualifies as an incident

An entry is included when credible reporting or primary documentation ties a reproducible Windows problem to a specific update, servicing change, or update-related rollout. Typical examples include:

• boot failures, blue screens, recovery loops, and lockouts;
• broken Windows features, drivers, networking, or applications;
• updates that fail to install or prevent later updates;
• serious regressions affecting performance, security, or data access;
• enterprise or hardware-specific failures with a documented trigger.

A complaint, isolated forum post, or coincidental failure is not enough on its own. The archive favors incidents with a named KB, a confirmed rollout, multiple credible reports, or acknowledgement in Microsoft documentation. The incident date is the date of the update that introduced the problem, not necessarily the date the problem was reported.

Severity definitions

Annoyance

A cosmetic, minor, or limited regression that does not generally stop the affected system or feature from doing its main job.

Broken

A feature, application, device, installation process, or important workflow genuinely stops working or becomes materially unreliable.

Catastrophic

The incident causes boot failures, blue screens, data loss, lockouts, or similarly severe loss of access or operation.

Severity describes the documented impact, not how many people were affected. A catastrophic failure can be limited to a particular model or configuration and still be catastrophic for those machines.

Sourcing and verification

Entries are researched from primary sources where available, especially Microsoft Windows release health pages, support articles, update history, and issue trackers. Reputable technical reporting is used to establish impact, affected configurations, user-visible symptoms, and timelines. Claims and KB attribution are cross-checked before publication when the evidence permits.

Every incident page links to its supporting material. Sources can be revised, moved, or corrected after publication, so readers should also consult the linked primary documentation before making operational decisions.

Fix status

Fixed means the archive has a sourced resolution for the documented incident, such as a later cumulative update, an out-of-band patch, a servicing change, or another confirmed resolution. Where known, the date shown is the date of that resolving change.

Unfixed means no complete resolution has been verified for the incident as summarized. It does not prove that no workaround or private fix exists, and status may lag new information. A mitigation, compatibility hold, or workaround is not automatically treated as a permanent fix.

Corrections and transparency

The site content, incident records, and revision history are public in the project’s GitHub repository. To report an incorrect date, KB number, severity, source, affected component, or fix status, open a GitHub issue with a link to supporting documentation. Pull requests with well-sourced corrections are also welcome.

The repository is the authoritative record of who changed the archive and when. This page makes no claim of institutional independence, exhaustive coverage, or formal affiliation with any vendor.
