Modify the registry using PowerShell _powershell

In the following example, PowerShell modifies the registry key value, completes the security loop disable, and Loopbackcheck disable.

Copy Code code as follows:

#Security loop Disable So, can look in it on the same machine
if ($gchn = Get-itemproperty "hklm:\system\currentcontrolset\control\lsa\msv1_0\"-name "BackConnectionHostNames"- EA silentlycontinue)-eq $null) {
New-itemproperty "hklm:\system\currentcontrolset\control\lsa\msv1_0\"-propertytype multistring-value "$url"-Name " BackConnectionHostNames "
}else{
Set-itemproperty "hklm:\system\currentcontrolset\control\lsa\msv1_0\"-name "BackConnectionHostNames"-Value ($gchn . backconnectionhostnames+ "$url")
}

#disable loobback Check
if ((get-itemproperty "hklm:\system\currentcontrolset\control\lsa\"-name "DisableLoopbackCheck"-ea silentlycontinue)-eq $null) {
New-itemproperty "Hklm:\system\currentcontrolset\control\lsa\"-propertytype dword-value "1"-Name " DisableLoopbackCheck "
}

Examples to everyone, below to share some PowerShell operation of the Registry method bar

Access registry key values

In PowerShell, a user can access a registry key by using a virtual drive similar to HKCU: (as HKEY_CURRENT_USER) and HKLM: (on behalf of Hkey_local_matchine).
such as: Dir Registry::hkey_local_machine\software
In this way, users can easily copy and paste the key values in the registry, the user can obtain the registered file suffix through the following command:
Dir registry::hkey_classes_root\.*-name | Sort-object

Reading registry key Values

In PowerShell, the user can process the contents of the registry as a virtual drive
The following get-regidtryvalues function enumerates all the key values stored under a registry key, as shown in the complete code:

 
function Get-registryvalues ($key) { 
         (Get-item $key). GetValueNames () 
}

Get-registryvalues hklm:\software\microsoft\windows\currentversion

Get-registryvalue reads any registry key value and returns its contents, as shown in the complete code:

function Get-registryvalue ($key, $value) { 
         (Get-itemproperty $key $value). $value 
}

Write registry key value

Adding or modifying registry keys is also handy in PowerShell, and the following is the complete code that creates the name Set-registryvalue function to manipulate the registry key value:

function Set-registryvalue ($key, $name, $value, $type = "String") { 
 if (Test-path $key)-eq $false) {MD $key | Out-null} 
    set-itemproperty $key $name $value-type $type 
 } 
  set-registryvalue hkcu:\software\testabc MyValue Hello 
  set-registryvalue hkcu:\software\testabc myvalue Dword 
  set-registryvalue hkcu:\software\ Testabc myvalue ' 
([byte[]][char[]] "Hello") Binary

Remove registry key value

By Remove-item Delete the target registry key, the complete code for the function Remove-registrykey is as follows:

function Remove-registrykey ($key) { 
remove-item $key-force 
}

To delete a registry value through the Remove-itemproperty function, the complete code looks like this:

function Remove-registryvalue ($key, $value) { 
remove-itemproperty $key $value 
}
