Windows 10: "Accidentally" changed permission to all C: files and folders

I might have made the most stupid mistake I've ever made. I was moving many files among different folders and every time I moved a file, a message appeared saying that I had to provide administrator permission to move the file. There are no other accounts on my PC so I'm the only user and admin. At the beginning I tried to ignore it, but then it became so annoying I searched in google for a way to revert this. Among the many "solutions" I found, there was one that said I had to "claim" ownership of the folder, I tried many times to no avail. So the stupid part in me thought it was a good idea

how to change folder and file permissions in windows 10

Hi David,



Thank you for contacting Microsoft Community.

• Are you trying to give permission to particular files and folders?

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

• Once you choose the file that you want to give permission, right click on it.
• Click on properties and go to security tab, check whether any permission have been set.
  
• After you have viewed the permissions that are already set, you can now click on the Advanced Button that is right below the "Permissions for Authenticated Users"
  
• Once you have clicked Advanced, a box like this should appear, the "Permission Entries" box, which shows all the permissions that are set for the users. Now, after you have spotted the user whose permissions you wish to change, click "Change Permissions.
• Click on the user you would like to edit, and then click the option that says "Change Permissions" which is right below the box.
• Once that is clicked, you are going to get the same box pop up, but this time, you can actually edit the options. You do that by clicking the "Administrators" user again, and this time, you are going to click the "Edit" option.

Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.

 

Folder and File default permissions

Hi Hilton,

When you changed folder permissions, all of its contents will also be affected. If you want to change permission on certain sub-folders, it is recommended to separate it up to one level and change only specific file or folder permissions which are
applicable to you.

To allow opening or modifying files, follow the steps below:

• Right-click a folder or file, then click Properties.
• Click the Security tab.
• Click Edit…
• Tick Allow or Deny, to manage permissions for your folder.
• Click OK to finish.

Let us know if this resolve your concerns.
