Solve Powershell Uninstall Error Count Issue

Over the past few weeks, some users have encountered the powershell Clear Error Count error message. This problem can occur for several reasons. We will review them below. The $Error automatic variable spans an array of error objects associated with the current session. An array can be passed to Get-Error with objects to get detailed error messages. In this example, $Error is passed to the Get-Error cmdlet.

  • PowerShell offers an automatic $error variable. He created a collection of errors that occur when running the PowerShell engine. The $error collection is an instance of System.Collections.ArrayList. The most recent error, the first error object in the collection is $Error[0]. The number of errors used is controlled by the $MaximumErrorCount effective variable (default is 256). You can increase this value to 32768, but this will also increase memory usage. The default value is usually quite large.

    What would you do if you wanted all entries to be bacteria-free before $error? $error is a variable, so your organization might want to try the Clear-Variable cmdlet:

    PowerShell Error: Leave These People Alone If you need to suppress an error, you can use the ErrorAction switch itself to suppress an important error for a single cmdlet, or the beautiful ErrorAction parameter variable to suppress problems globally.

    What if you really want to clear all entries in $error? $error is an element, so you can try this cmdlet Clear-Variable: PS> Clear-Variable-Error -Force Clear-Variable: Distinction-Error cannot be overridden because it is read-only or stable.

    $error is also an object, so I think the Get-Member cmdlet will reveal any useful method:

    Alternatively, to remove a variable along with its value, use Remove-Variable Remove-Item.
