PowerTip: Set ErrorActionPreference to original value

Summary: Cloud & Datacenter Management MVP, Thomas Rayner, shows how to work with the ErrorActionPreference variable in Windows PowerShell.

 I have a script that requires me to change the ErrorActionPreference variable, but how can I set it to its original value after the script is done?

 Store the current value of $ErrorActionPreference and set it again later:

$OldEAP = $ErrorActionPreference

$ErrorActionPreference = ‘silentlycontinue’

#Your script runs in here

$ErrorActionPreference = $OldEAP
