Winqual
Windows Quality Online Services (Winqual) was a Microsoft web service providing a developer dashboard to certification for the Microsoft Windows logo programs and access to the Windows Error Reporting (WER) data. In preparation for Windows 8 the Winqual site was retired and its features were rolled together with an interface for creating a developer account and managing your Windows Store Apps called Windows Dev Center.
End-users may have accessed the Winqual site through windows error reporting response links or other references to the infrastructure in the Windows Error Reporting systems.
