Sidchg64.rarl: The Ultimate Guide to Modify Local Computer SID and Other Identifiers


Sidchg64.rarl: What Is It and How to Use It?




If you have ever cloned or restored a Windows computer, you may have encountered some problems with its SID or Security Identifier. SID is a unique value that identifies each computer and user account in Windows. Having duplicate SIDs can cause conflicts and errors in your network or domain. To avoid this, you need to change the SID of your cloned or restored computer. But how do you do that? One of the tools that can help you is Sidchg64.rarl.




Sidchg64.rarl



Sidchg64.rarl is a command-line utility that can modify local computer SID and computer name for Windows 10/8.1/8/7/2008 R2 and later versions. It can also change other identifiers such as WSUS ID, Machine GUID, Device ID, MSDTC CID, Dhcpv6 DUID, SQL Server Master database, etc. It can preserve encrypted files, certificates, credentials, Windows Action Center settings, etc. after SID change. It can also reset OneDrive or McAfee ID if needed.


In this article, we will explain what Sidchg64.rarl is and how to use it, what are the benefits and risks of using it, and answer some common questions about it. By the end of this article, you will have a better understanding of Sidchg64.rarl and how to use it effectively.


What is SID and why does it need to be changed?




SID stands for Security Identifier and is a unique value assigned to each computer and user account in Windows. It is used to identify and grant access rights and permissions to resources and objects in the system. For example, when you log in to your computer, Windows checks your SID against the security database to verify your identity and privileges.


SID needs to be changed when cloning or restoring a computer to avoid conflicts and errors in the network or domain. If two or more computers have the same SID, they may not be able to join the domain, access network resources, or receive updates properly. They may also pose a security risk as they can impersonate each other or cause authentication failures.


Changing the SID of a computer is not a simple task and requires a special tool that can modify the registry and other system files without causing damage or corruption. One of the tools that can do this is Sidchg64.rarl.


What is Sidchg64.rarl and how does it work?




Sidchg64.rarl is a command-line utility that can modify local computer SID and computer name for Windows 10/8.1/8/7/2008 R2 and later versions. It is developed by Stratesave Systems, a company that specializes in backup and restore software for Windows servers and workstations. Sidchg64.rarl is part of their Stratesave Backup Software package, but it can also be purchased separately or obtained from other sources.


Sidchg64.rarl can also change other identifiers such as WSUS ID, Machine GUID, Device ID, MSDTC CID, Dhcpv6 DUID, SQL Server Master database, etc. These identifiers are used by various applications and services to identify and communicate with the computer. Changing them can help resolve some issues or improve performance after cloning or restoring a computer.


Sidchg64.rarl can preserve encrypted files, certificates, credentials, Windows Action Center settings, etc. after SID change. These are some of the data that are tied to the original SID of the computer and may become inaccessible or invalid after SID change. Sidchg64.rarl can keep them intact and functional by updating their references to the new SID.


Sidchg64.rarl can also reset OneDrive or McAfee ID if needed. These are some of the applications that use their own IDs to identify and sync with the computer. If these IDs are duplicated on multiple computers, they may cause conflicts or errors. Sidchg64.rarl can reset them to new values after SID change.


How to download and use Sidchg64.rarl?




Sidchg64.rarl can be downloaded from the official website of Stratesave or from other trusted sources. The file size is about 1 MB and it comes in a compressed format with the extension .rarl. This is a special format that can be extracted by Stratesave Backup Software or by using a free tool called RARL Extractor. After extracting the file, you will get a single executable file called sidchg64.exe.


Sidchg64.rarl requires a license key to run, which can be purchased from Stratesave or obtained from other sources. The license key is a 16-digit alphanumeric code that needs to be entered when running sidchg64.exe for the first time. The license key is valid for one computer only and cannot be transferred or reused on another computer.


Sidchg64.rarl can be run from a command prompt with various options and parameters to customize the SID change process. You need to have administrator rights to run sidchg64.exe and you need to restart the computer after running it. Here are some of the basic syntax and examples of using sidchg64.exe:



OptionDescriptionExample


/keySpecifies the license keysidchg64 /key ABCD-EFGH-IJKL-MNOP


/rGenerates a random SIDsidchg64 /r


/sSpecifies a custom SIDsidchg64 /s S-1-5-21-1234567890-1234567890-1234567890


/nSpecifies a new computer namesidchg64 /n NEW-PC


/dSpecifies a new computer descriptionsidchg64 /d "This is a new computer"


/oSpecifies other identifiers to changesidchg64 /o WSUSID,SQLDB


/pSpecifies data to preserve after SID changesidchg64 /p EFS,CERTS,CRED


/xSpecifies applications to reset after SID changesidchg64 /x ONEDRIVE,MCAFEE


/qRuns sidchg64 in quiet mode (no output)sidchg64 /q


/h or /?Displays help informationsidchg64 /h or sidchg64 /?


You can combine multiple options and parameters in one command, as long as they are separated by spaces. For example, you can run the following command to generate a random SID, change the computer name and description, change the WSUS ID and SQL Server Master database, preserve the encrypted files and certificates, and reset OneDrive and McAfee ID:



sidchg64 /r /n NEW-PC /d "This is a new computer" /o WSUSID,SQLDB /p EFS,CERTS /x ONEDRIVE,MCAFEE


You can also run sidchg64 without any options or parameters to display the current SID and computer name of your computer. For example, you can run the following command to see the current SID and computer name:



sidchg64


The output will look something like this:
