Windows 10: Friend Accidently put System32 on Controlled Folder Access and can't use computer now

Hi, a friend told me that their dad added the System32 Folder to Controlled Folder Access. Now the computer is unusable. Is there anyway to fix this so that he can use the computer again or do we need to reinstall the computer?

?? How do I PW protect Folders in windows

hmmm?
Sharing files and folders overview You can share the files and folders stored on your computer, on a network, and on the Web. The method you choose depends on whom you want to share files with, and what computer they will use to access the files.

When you share files or folders, they are not as protected as they are when you do not share them. People with access to your computer or your network might be able to read, copy, or change files that are in a shared folder. You should always be aware that the files and folders that you share are available to other people and be sure to monitor your shared files and folders on a regular basis.

Important

If your computer is not joined to a domain, you can use the Network Setup Wizard to automatically turn file and printer sharing on or off. To start the Network Setup Wizard, click Start, click Control Panel, click Network and Internet Connections, and then click Network Setup Wizard.
If you both use the same computer

You can put the files you want to share in the Shared Documents folder. Files stored in the Shared Documents folder or its subfolders are always available to other users on your computer.

Step-by-step procedure
Note

If you are connected to a network domain, the Shared Documents, Shared Pictures, and Shared Music folders are not available.
If both computers are on the same network

You can share a folder or drive on your computer with others on the network. You can also control whether the files in the shared folder can be modified by other users.

If your computer is connected to a network domain, use this procedure:

If your computer is connected to a workgroup, use this procedure:

Step-by-step procedure
Note

If you are connected to a network domain, you will need to set the Access control for the folder or drive after sharing it. For more information, go to To set, view, change, or remove file and folder permissions.
If you want to share your files online

You can publish pictures and documents on the Web using the Web Publishing Wizard. The files will be stored in a private, online folder that you manage.

Step-by-step procedure

If you don't want others to access your files

You can prevent other users from accessing your folders and the files they contain. When your computer is connected to a domain, this is called setting permissions for your file or folder. When your computer is connected to a workgroup, this is called making your folders private.

If your computer is connected to a network domain, use this procedure:

If your computer is connected to a workgroup, use this procedure:

How to gain full control over the system32 folder?


Hello

Thanks for your replies and concerns.

If I type this in Windows PowerShell

Code:

Code:

Get-ChildItem C:\ -Recurse | Where {$_.extension -eq “.mp4”} | ForEach-Object { $_.FullName }

I should get a list on screen of all MP4 files on my C drive. The file extension is irrelevant. Instead, I get this:

That is, I do not have permission to access RtBackup which is a folder in system32 and so, I am prevented from working as I should be able to in PowerShell.

If it's possible to have full control over that RtBackup folder - without having control over the entire system32 folder, - then that would be fine.

How would I do that, please?
