Windows Error Reporting (WER) is a feature of Windows, which enables users to notify Microsoft of application problems and sometimes (if not at no time) to get a solution back.

Windows is checking for a solution to the problem...

A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.

How to disable WER?

If you ever want to disable Windows Error Reporting, you may open regedit.exe, navigate to the per-machine key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting

or the per-user key

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\Windows Error Reporting

find/add the value with name Disabled and type REG_DWORD, and set its data to 1.

Why disabling WER?

With Windows Error Reporting disabled, you basically get 2 main advantages:

  1. Wait no more before the close/debug dialog appears.

    A problem caused the program to stop working correctly. Please close the program.

  2. Save disk space.

    When WER is enabled, each application crash or unresponsiveness will generate a report with application parameters and related data. They are generally stored in C:\ProgramData\Microsoft\Windows\WER.

    However, when WER is disabled, no more reports get generated, thus disk space is saved.
