Windows 10: How to reset all user permissions for Windows 10?

I made a bad mistake and I removed both permissions for the SYSTEM and for administrators on my local disk c drive. How can I fix it?

Windows 10 permissions...

How is the NAS on windows 10 Pro? Is it software or a share? Did you check ntfs vs share permissions?

 

Windows 10 permissions...

Ok so I feel officially dumb I am trying to copy my steam library to my NAS. Both are on windows 10 pro and both have full control in the file manager. Neither windows nor fast copy will allow me to copy, both list a permissions error? This was never an issue with windows 7...so first off thank you microsoft god forbid I want to back up my data, second off what the heck do I need to do to make this work. All I could fine online was to set full control and that obviously didn't help.

Also robocopy doesn't apparently work with network locations?

 

Reset Windows 10 file permissions to default

Hi,

Welcome to Microsoft Community and thank you for your interest in Windows 10.

• Are you receiving any error message while accessing any files?

I suggest you to follow the below methods and check if it helps.

Method 1: Startup troubleshooter.

• Open the Task manager. Here’s a tip: Press CTRL+Shift+ESC.
  
• Click File > Run New Task
• Make sure you have a check mark beside “Create this task with administrative privileges”
• Type Powershell
• Type the following in the Powershell prompt:

$manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest


6. Close the Powershell window

7. Reboot

Method 2: If you are facing issues accessing files, then I suggest you to follow the below steps and check if it helps.

This may be caused by incorrect permissions on the files.

You can fix this using these steps:

• Open the properties of the main user profile folder where the files are located (such as Documents, Pictures, etc).
  
• Go to the Security tab and click Advanced.
• Check the box at the bottom of this window. It is labeled "Replace all child object permissions with inheritable permissions from this object" and then click Ok
