How i search all values and/or registry keys of a term with powershell to do mass deletion ou replacement?

This is my prototype. If you like it, I can make a function form it, so that it's easier to use.

You can set the $search and $root to test it.

$search = "arial"
$root = 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion'

Get-childItem $root -Recurse -ErrorAction silentlycontinue | %{
    if($_.name -match $search){
        New-Object -TypeName PSObject -Property @{
                    Path = $_.name
                    Name = $null
                    Value = $null
                    Type = $null
                }
            }
    else{
        $key = $_
        $key.getvaluenames() | %{
            if($_ -match $search){New-Object -TypeName PSObject -Property @{
                    Path = $key.name
                    Name = $_
                    Value = $key.getvalue($_)
                    Type = $key.getvaluekind($_)
                }
            }
        }
    }
} | Select-Object path,name, value, type

Wonderful soostibi!!!

How can i save and call the SearchRegistry function ?

Thank you

It didint worked.

Let's describe my steps:

(enable custom scripts)
1 - PS E:\> set-executionpolicy unrestricted

(the complete script solution)
2 - PS E:\> .\11scr.ps1

(for test)
3 - PS E:\> SearchRegistry -search Microsoft -root HKCU:\Software -recurse $false | Format-Table

Bad result, the log:

PS E:\> get-help set-executionpolicy
PS E:\> set-executionpolicy unrestricted

Execution Policy Change
The execution policy helps protect you from scripts that you do not trust. Changing the execution policy might expose you to the security risks described in the about_Execution_Policies
help topic. Do you want to change the execution policy?
[Y] Yes  [N] No  [S] Suspend  [?] Help (default is "Y"): y
PS E:\> .\11scr.ps1
PS E:\> SearchRegistry -search Microsoft -root HKCU:\Software -recurse $false | Format-Table
The term 'SearchRegistry' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the p
ath is correct and try again.
