Windows 10: permission in system to delet a old file

I am trying to delete windows old and it says I must get permission in system. Can someone tell me how??

:)

 

File permissions to delete file

I am trying this, but it's taking a very long time.

 

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:

Code:

icacls "C:" /t /c /q /RESET

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

Followed by this command once completed:

Code:

Code:

icacls "c:\" /t /c /q Administrators:f

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.

 

Needing permission from SYSTEM to delete windows old.

When you used disk cleanup, did you click the button to clean up old system files?
