PowerShell Help

Have this working with invoke command but not as local command.

The commands with the # was working on my desktop but I run this script on the server. So I needed to convert the commands to local commands

[pre]

$Results += $(“” | Out-String)
$Results += ‘Server TGCS012’ | out-string
try
{
#$results += invoke-command -computer TGCS012 -scriptblock {reg delete “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager” /v PendingFileRenameOperations /f} -ea Stop
#$results += invoke-command -computer TGCS012 -scriptblock {(Get-ItemProperty -Path ‘Registry::HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager’ -Name PendingFileRenameOperations ).PendingFileRenameOperations} -ea Stop
$results += reg delete “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager” /v PendingFileRenameOperations /f
$results += (Get-ItemProperty -Path ‘Registry::HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager’ -Name PendingFileRenameOperations ).PendingFileRenameOperations

}
catch { $Results += $_.exception.message}

[/pre]

Any ideas

 

Thank you

You need to clear the basic concept of error handling. Please read this document. Each and every line is important.

Not really able to understand the question. The title and post content is confusing. Can you elaborate a little more on the expectation from your script.

Just a suggestion that may or may not help - check out using Remove-Item instead of “reg delete” to remove a registry key.

I like to use PowerShell cmdlets whenever I can, instead of going back to older commands.

[pre]

PS C:\util> $Results += Remove-item ‘hklm:\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations’
-ea Stop
Remove-item : Cannot find path ‘HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations’
because it does not exist.

[/pre]

The command in a DOS Windows worked

C:>reg delete “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager” /v PendingFileRenameOperations /f
The operation completed successfully.

How to get this to work in powershell?

You would use Remove-ItemProperty to do this.

# Take a backup of this registry key before testing.
Remove-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager' -Name PendingFileRenameOperations -WhatIf
# Remove -WhatIf to take the action.
