Windows Error Reporting (WER)

On this page

Recommendation

Depends

Can be disabled for privacy on a stable PC if you do not send reports to developers.

When troubleshooting crashes of a game, driver or application, it is better to leave WER enabled so as not to lose diagnostic data.

What changes

Section titled “What changes”

Windows Error Reporting (WER) is a feature that, when an application or component crashes, or when a program hangs, collects information about the error and offers to send it to Microsoft for analysis. According to Microsoft documentation, this covers application crashes, kernel crashes and unresponsive programs. Once disabled, when an application crashes, the prompt to send a report does not appear, and no data is sent. The setting does not prevent the crash itself, and ordinary events from Windows logs are not deleted.

Exceptions and differences

Section titled “Exceptions and differences”

The setting works in Windows 10 and Windows 11. The standard way to manage this feature in Windows is in “Settings” → “Privacy & security” → “Diagnostics & feedback” (in Windows 10 — “Settings” → “Privacy” → “Diagnostics & feedback”). The diagnostic data that Microsoft collects at the system-wide level is configured separately — “Telemetry in the data collection policy”.

How to verify the result

Section titled “How to verify the result”

Wait for or trigger a crash of any third-party application: the dialog offering to tell Microsoft about the problem and send a report does not appear.

How to change and revert

Section titled “How to change and revert”

Open “Optimization” → “Privacy” → “Windows Diagnostics and Reports” → “Windows Error Reporting (WER)”, move the toggle to the “Enabled” position: BoosterX will apply the disabling of WER — the prompt to send a report on a crash no longer appears. Click “Apply”. With “Instant apply” enabled, a separate button is not required. To revert, move the toggle to the “Disabled” position and apply the change again: BoosterX will return Windows to its default state with WER working.
