When a customer gets a new server and decides to reuse current workstations or PCs, it is important to update the registry keys and values that refer to the old server name. This article will focus on how to delete registry keys and values containing specific strings such as "CMD", "PowerShell", "Workstation/PC Server Name", and "Migration". The article will be site-focused with a global topic and will cover key concepts related to this subject. It will be at least 800 words long and will include subtitles, paragraphs, and code blocks.

Registry Keys and Values
A registry key is a container that holds a set of values, which are referred to as registry values. Each value has a name and a data type, and the data can be a string, a binary number, a DWORD (32-bit) or a QWORD (64-bit) value, or a list of multistring values.
The Windows Registry is a hierarchical database that stores low-level settings for the Microsoft Windows operating system and for applications that opt to use the registry. The kernel, device drivers, services, Security Accounts Manager, and user interface can all use the registry.
Finding Registry Keys and Values Containing Specific Strings
To find registry keys and values containing specific strings, you can use the reg command-line tool in Windows. Here's an example of how to use the reg command to find registry keys and values containing the string "servername":
reg query HKU\*\ /f servername /t REG\_SZ /s
In this example, the reg command is used with the query option to search all user hives (HKU\*) for registry keys and values containing the string "servername". The /f option specifies the string to search for, the /t option specifies the data type to search for (in this case, string values), and the /s option searches subkeys recursively.
Deleting Registry Keys and Values Containing Specific Strings
To delete registry keys and values containing specific strings, you can use the reg command-line tool in Windows. Here's an example of how to use the reg command to delete registry keys and values containing the string "servername":
reg delete HKU\*\ /f servername /t REG\_SZ /s
In this example, the reg command is used with the delete option to delete registry keys and values containing the string "servername". The /f option forces the deletion, the /t option specifies the data type to delete, and the /s option deletes subkeys recursively.
PowerShell Script to Delete Registry Keys and Values
PowerShell can also be used to delete registry keys and values containing specific strings. Here's an example of a PowerShell script that deletes registry keys and values containing the string "servername":
$registryPath = "HKU:\*"
$searchString = "servername"
$dataType = "REG\_SZ"
Get-ChildItem -Path $registryPath -Recurse | ForEach-Object {
if (($_.GetValue($searchString) -ne $null) -and ($\_
