Define the problem first
- Application crashes and startup errors
- Recent installations or configuration changes
- Storage, update and software health
- Recovery options before significant changes
Use the symptom to choose the repair
Windows errors can come from applications, updates, storage problems or an interrupted configuration change. Record the exact error and when it appears. Include whether the computer starts normally, whether a single application is affected and whether the issue began after a known change.
Tell support which files and applications must be preserved and what recovery options are available. Repeatedly running cleanup utilities can make it harder to understand what changed. An assessment should identify the relevant cause and an appropriate repair rather than treating every problem as a registry fault.
Before we get started
Avoid making broad registry changes without understanding their effect. Share the exact error and any attempted fixes so support can choose an appropriate next step.
