Windows Hardware Error Architecture (WHEA) Cmdlets in Windows PowerShell

Applies To: Windows 8, Windows Server 2012

The Windows Hardware Error Architecture (WHEA) cmdlet enables you to get and set WHEA memory policy values. These policies control how WHEA reacts to corrected and uncorrected memory errors. Some of the WHEA policy values affect the Predictive Failure Analysis (PFA) performed by WHEA on corrected ECC memory errors.

By using PFA, WHEA can monitor one or more Error Correcting Code (ECC) memory pages for errors. If the number of errors on a page exceeds a configurable threshold within a configurable time interval, WHEA attempts to take the memory page offline. For more information about WHEA, see Windows Hardware Error Architecture Overview.
