# TechClassy

> Windows errors, diagnosed clearly.

TechClassy is a local-first, deterministic Windows diagnostic and evidence-reading utility. It separates confirmed facts from unconfirmed causes, asks one context question, returns one source-backed safe check, then records the actual observation separately from whether the original problem was reproduced. Self-service is bounded: one first check plus at most one bounded follow-up, ending in stop, monitor, or evidence-backed escalation—never an open-ended repair chain. A browser-local Diagnostic Evidence Pack preserves the selected context, action, before/after observations, task-specific evidence, reviewed sources, and stop boundary, and a validated Resume Capsule restores a session locally without an account or stored data.

## Primary tools
- [Error Checker](https://techclassy.com/windows-error-code/): Recognize a code, exact message, driver filename, Stop Code, or command result and route it to the right diagnostic family.
- [Update](https://techclassy.com/windows-update-error/): Separate download, install, restart, servicing, space, connectivity, and upgrade rollback evidence.
- [Device](https://techclassy.com/device-manager/): Interpret Device Manager status only after identifying the affected device category.
- [BSOD](https://techclassy.com/stop-code/): Identify the confirmed bug-check family, capture recurrence context, and collect usable crash evidence without guessing a root cause.
- [Command Output](https://techclassy.com/command-output/): Parse the final SFC or DISM status locally and show the next evidence checkpoint before any administrator repair step.

## Evidence readers
- [Windows Event Viewer Error Parser](https://techclassy.com/windows-event-viewer/): Paste one time-matched Event Viewer record as rendered text or XML and extract the provider, Event ID, time, level, faulting fields, and diagnostic tokens without uploading the event.
- [Windows Update & CBS Log Evidence Parser](https://techclassy.com/windows-update-log-parser/): Paste a short WindowsUpdate.log, CBS.log, DISM, or servicing excerpt and extract timestamps, components, KBs, packages, error codes, and repeated error clusters without uploading the log.
- [Windows System Information Snapshot Reader](https://techclassy.com/windows-system-information/): Paste a bounded msinfo32 or DxDiag text report and extract the Windows build, system model, firmware mode, memory, DirectX, display-driver, and explicitly reported problem-device facts without uploading the report.
- [Windows Driver Identity & Package Reader](https://techclassy.com/driver-identity/): Paste bounded driverquery or PnPUtil enumeration text and extract driver, package, provider, class, version, signer, state, path, and device-relation facts without recommending a download or naming a culprit.
- [Windows Known Issue Checker](https://techclassy.com/windows-known-issue-checker/): Enter a Windows version/build, installed KB, and exact symptom to compare them with a bounded, dated Microsoft Release Health snapshot without claiming that a matching record proves this device is affected.
