Windows 10: Windows 10 File deletion needs System Administrator Permission

I am the sole user of my computer. I cannot delete a file (or file folder) as to do so needs System Administrator Permission.

I am the Administrator.

How to I fix this?

File permissions to delete file

This command restores permissions to default for all files contained within C:\ quietly.

Followed by this command once completed:

Code: icacls "c:\" /t /c /q Administrators:f[/quote] This command restores full permissions to the Administrators on the computer, which I presume you are an Administrator.

And reboot the computer, and finally attempt to delete the file after attempting to retake ownership.

If that does not work, then I suggest using a third party utility known as UnlockIT:
Downloads - UnLock IT

And download, install. Ensure you select customized installation.

Right click the folder that contains the files or the files individually that you would like to delete, and follow as here:






Then this should delete all files you right clicked upon after restarting the system.

You should not run into issues regarding permissions after this, and if you do, post again and I'll look into it.

Side note: often times malware tends to hijack a system and fluff itself in permissions that benefit itself.[/quote] I am trying this, but it's taking a very long time.

 

System administrator permissions to delete files

hello enya77

please follow these steps and let me know if helps

Give Permission to the folder/drive that you are facing the issue with.

In Windows Explorer, right-click the file or folder you want to work with.

From the pop-up menu, select Properties, and then in the Properties dialog box click the Security tab.

In the Name list box, select the user, contact, computer, or group whose permissions you want to view. If the permissions are dimmed, it means the permissions are inherited from a parent object.

Turn off UAC (User Account Control)

Before you can do anything, you must turn off the UAC, or you will be locked out of the following steps.

1) Start -> Settings -> Control Panel -> User Accounts

2) Click "Change User Account Control Settings"

3) Move slider all the way down to "Never Notify"

4) Reboot

2) Take Ownership

Yes take ownership. Even though you are logged on as an Administrator, you can't change files that don't belong to you. The Program Files folder is set to the Trusted Installer group and the Administrator doesn't have the rights to change anything. So now we
have to claim all the files and folders.

1) Open Windows Explorer

2) R-Click on Program Files -> Properties -> Security Tab

3) Click Advanced -> Owner

4) Click Edit

5) Select Administrators -> Put a checkmark in Replace owner on subcontainers & objects -> Apply

6) Wait a while.....

7) When it finishes, Click OK on all boxes to close everything

3) Fix Permissions

Now that you own the files, you have to give yourself permission to modify them

1) R-Click on Program Files -> Properties -> Security Tab

2) Click Advanced -> Change Permission

3) Select Administrators (any entry) -> Edit

4) Change the Apply To drop down box to This Folder, Subfolder & Files

5) Put check in Full Control under Allow column -> OK -> Apply

6) Wait some more.....

7) When it finishes, the dialog boxes may hide behind the Explorer window. Minimize it and click OK on all the the dialog boxes

 

File permissions to delete file

Windows is extremely confusing in its permissions and file ownership.*Sad

If Taking Ownership of the files does not work, then the ACL and permissions are misconfigured.

Permissions precedes the ownership, you can have ownership but incorrect permissions in accordance with the ACL Access Control Lists (Windows).

Microsoft - How Permissions Work

I suggest that you open powershell (Search > type powershell > Right click > run as admin) and execute this command:

Code: icacls "C:" /t /c /q /RESET[/quote] This command restores permissions to default for all files contained within C:\ quietly.

Followed by this command once completed:

Code: icacls "c:\" /t /c /q Administrators:f[/quote] This command restores full permissions to the Administrators on the computer, which I presume you are an Administrator.

And reboot the computer, and finally attempt to delete the file after attempting to retake ownership.

If that does not work, then I suggest using a third party utility known as UnlockIT:
Downloads - UnLock IT

And download, install. Ensure you select customized installation.

Right click the folder that contains the files or the files individually that you would like to delete, and follow as here:






Then this should delete all files you right clicked upon after restarting the system.

You should not run into issues regarding permissions after this, and if you do, post again and I'll look into it.
