So i found a Tool Named RegRestorer in Github and what i wanted to Know is it Malicious ?
It has a Open Source Code Any One Of you Can Check it out

Looks like a recovery tool, but these tools are highly invasive and their use is not recommended.

If you are looking to recover a system, either use an image, or use the built-in recovery tools that Windows has on boot.

Is there any specific problem you’re trying to solve?

I just Found it And Tested it against a Persistent Malware Such As NoEscape Trojan (Endermanch)
And it Works Flawlessly
Not a Problem i want to Solve
But i was Surprised That The Tool Cleaned Everything up If the VM Wasn't Even Infected In The first Place
So That is Why i Wanted To Share My Find With The Community
And also Because this thing Edits the Registry Of Course it will be Highly Invasive
And i Noticed that It is Extremely Aggressive But Hey it Gets The Job Done

Then have you seen this:

Btw there is a reason why most AVs do not tamper with the registry too much, some are even scared to remove the run keys for malware (despite the file being removed). Tampering with the registry can cause severe issues, it can even render the system unbootable.

For my tool, I am only covering a few sections of the registry to prevent these “file not found errors”. If you don’t know what exactly the malware wrote, it is not recommended to perform some of these actions.

i know that The Registry is Sensetive and it Can Brick Your Machine if you
Make the Wrong Move and Let me tell you something
I have dealt with a Good amount of MBR Writing malware and Persistent Malware
And looking at its Source Code it dosent Delete anything it seems
But the Values malware virus trojan which dosent even exist in the Registry
In the First Place
And i tested this Tool on a Infected Win10 Win11 (VM's)
And both Did not Get Bricked they Rebooted Fine
So is this Tool Safe ? well As He Said in the Readme
this Tool is only meant for Sysadmins and Security Professionals
So this tool isnt For Casual Use too
From My Experience this Tool Was Effective

In the cpp file there is nothing malicious, in terms of data exfiltration or data destruction. The tool does what it says on the tin.

 

[Divergent]

It is not malware but an aggressive tool intended for advanced users to revert system-level changes made by malicious software. Its core function is to modify the Windows Registry to restore security settings, re-enable disabled system tools, and remove common malware persistence mechanisms. The tool's author explicitly warns that its behavior mimics malware and is expected to trigger antivirus alerts. While benign in intent, its highly invasive operations carry a risk of system instability if used improperly.

Numerous strings confirm the tool's stated purpose as a system repair utility.

UI elements and status messages

"Run Recovery Plan", "Reactivating Windows Defender", "Restore System Tools (CMD, Registry, Task Manager)", "Removing Malware Persistence", "Recovery completed successfully!".

Registry keys and values targeted for repair

SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System, DisableTaskMgr, DisableCMD, DisableRegistryTools, SOFTWARE\Microsoft\Windows Defender, DisableAntiSpyware.

External commands

reagentc /enable, gpupdate /force, sc config %s start= auto.

Packer Information

There is no evidence of packers or obfuscation. The code is transparently available.

RegRestorer.exe is a legitimate system remediation tool developed for cleaning up a Windows machine after a malware infection. Its operations are transparent and align perfectly with its stated purpose. While it is not malicious, its functions are highly invasive and directly modify critical areas of the operating system. It should only be used by knowledgeable professionals who understand the changes it makes, as improper use could lead to unintended system behavior.

Sometimes there are cases where a Simple System Restore can help undo the Changes of Malware Infection.

Yeah i went through it code and yes it has Nothing Malicious in it
And as i said before Registry Operations cant be anything but Invasive it has to be Invasive
That is Inevitable
And lets be Honest the Tool is Great after a Infection

Yeah good thing this tool is actually doing what is says

i agree
But not all of us have a System Restore Point

Oh and sorry i just Noticed this
I am Impressed by Your Tool to be honest
But Be Careful you can Delete Legitimate Apps/Reg Keys/etc
So try make the Tool Leap into the Precision side

True. Sometimes it gets corrupted for unknown reason making sys restore impossible.

Provided that this simple recovery, post infect tool is 100% efficient in returning the settings to previous working conditions, how can it repair on a system where file associations EXE ESPECIALLY would be trashed? In my opinion another option could be to apply at least SOME fixes via a PE Boot Disk if possible, then on entering GUI afterwards that user could use this to recover the other settings.

Just looking at it from worse case scenario perspective.
